<span>A store display rotates 40 times every half hour i.e 30 minutes
Thus, by simple calcultion, we say,
Therefore, the store display rotates 80 times in 1 hour i.e. 60 minutes
Now, 
Thus, the strore display will rotate 80*4 = 320 times in 4 hours

therefore, the answer is 320 times in 4 hours</span>

Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were all
Sergio039 [100]
Let events
A=Nathan has allergy
~A=Nathan does not have allergy
T=Nathan tests positive
~T=Nathan does not test positive

We are given
P(A)=0.75  [ probability that Nathan is allergic ]
P(T|A)=0.98  [probability of testing positive given Nathan is allergic to Penicillin]

We want to calculate probability that Nathan is allergic AND tests positive
P(T n A)

From definition of conditional probability,
P(T|A)=P(T n A)/P(A)
substitute known values,
0.98 = P(T n A) / 0.75
solving for P(T n A)
P(T n A) = 0.75*0.98 = 0.735

Hope this helps!!
