For this case, as Josh worked more than 40 hours, he was able to receive a payment ($ 8.20 / h) * (40 h) = 328 1.5(8.20) *8.75 = <span>
<span>107.625 </span></span> 328+107.625= 435.625 the gross earnings for Pruitt are 435.625 $
So what is the probability of the selecting the first coin? There are total of 4 different coins, so the probability of getting a dime is 1 out of 4, then he replace it, then again the probability stays the same, he still has 1 out 4 chance of getting a dime. So then it's just 1/4*1/4=1/16 :)
