Two cards are drawn without replacement from a well-shuffled, standard deck of 52 playing cards. What is the probability of choosing two hearts? Recall that there are 13 hearts in a deck. Round to four decimal places as needed.

Suppose you have a jar of change on your desk. The jar contains: 20 pennies, 15 nickels, 12 dimes and 28 quarters. If you reach into the jar and randomly grab three coins in succession, without replacement, what is the probability that all three are dimes? Round to 4 decimal places as needed. 

A pro-golfer hits a golf ball 8 times. The speed of the club head is recorded for each hit, as well as the distance the ball travels. Calculate the correlation coefficient, rounding to three decimal places as needed. Club head speed (MPH) Distance (Yds) 94 109 95 100 99 122 100 113 103 128 104 119 108 132 112 137

A pro-golfer hits a golf ball 8 times. The speed of the club head is recorded for each hit, as well as the distance the ball travels. Using the least squares regression equation, estimate the distance the ball travels if the golfer hits the ball with a club head speed of 101 mph. Round to the nearest tenth of a yard as needed.  Club head speed (MPH) Distance (Yds) 94 109 95 100 99 122 100 113 103 128 104 119 108 132 112 137

During routine batch review following granulation, production personnel identify a short-duration processing variation that was assessed as having no immediate impact on finished product quality or process performance. According to deviation management requirements, how should this event be managed?

The following text appears in the Procedure section of the SOP on Distribution of SOPs as one step:“6.4 The RAP/QAP will issue the controlled SOP, stamped “COPY”. The sequential copy number of SOP made is entered manually into the header of the copied SOP, on each page. The RAP/QAP will retrieve any previous SOP from the personnel or area and physically strike through it and shred it.”(RAP: Regulatory Affairs Pharmacist, QAP: Quality Assurance Pharmacist)As Checker (reviewer) of the SOP (before authorisation), review the extract of the Procedure section above and rewrite/edit it appropriately, also indicating the responsibilities.

A pharmaceutical company has introduced a new automated purified water storage and distribution system for use in the manufacture of non-sterile oral liquid medicines. The engineering department confirms that the system has been mechanically installed and is operational. Due to production delays and increasing customer orders, operations personnel request permission to immediately begin using the system for routine manufacturing activities.During a Quality Assurance review meeting, the Responsible Pharmacist (RP) states that the system may not be used until the appropriate qualification activities have been completed and approved in accordance with GMP requirements.List and briefly describe the qualification stages that should be completed before the purified water system is approved for routine pharmaceutical use.  (12)Discuss why qualification of pharmaceutical utility systems is important in maintaining GMP compliance and product quality. (6)
