1. 1/2 probability of tossing tails and 1/6 probability of rolling a 6

1/2 * 1/6 = 1/12 probability of both

2. 1/2 probability of heads and 1/6 probability of rolling a 5

1/2 * 1/6 = 1/12 probability of both

A lot of 100 semiconductor chips contains 15 that are defective. three chips are selected at random from the lot without replace

Alex787 [66]

D=event that chip selected is defective
d=event that chip selected is NOT defective

Four possible scenarios for the first two selections:
P(DDD)=15/100*14/99*13/98=13/4620
P(DdD)=15/100*85/99*14/98=17/924
P(dDD)=85/100*15/99*14/99=17/924
P(ddD)=85/100*84/99*15/98=17/154

Probability of third selection being defective is the sum of all cases,
P(XXD)=P(DDD)+P(DdD)+P(dDD)+P(ddD)
=3/20

1. $5.76/64 Ounces
2. $1.80/15 Ounces

1. $0.09/ounce
2. $0.12/ounce

So, in conclusion, the 64 ounce bottle is cheaper than the 15 ounce bottle by $0.03.
