Math Help!?

A cellular phone manufacturer randomly selects 5 of every 50 phones from the assembly line and tests them. If at least 4 out of 5 pass inspection, the batch of 50 is considered acceptable. Fine the probability that a batch of 50 phones is considered acceptable given the following additional information:

1. the batch of 50 phones contains 2 defectives

2. the batch contains no defectives

for number 1, I got .21

number 2 I got .311

Is this right??

#2 that the probability of it being acceptable is 100%

#1 would be around 98 %

Just take the number, divide it by 100 and multiply in the number of acceptable phones.
