1/7 of all people are allergic to Tylenol. If 4 people are selected at random, find the probability that all four people are not allergic to Tylenol.
Thank you for the opportunity to help you with your question!
1/7 allergic to Tylenol
those not allergic are 6/7
if 4 people are selected then it will be 6/7*4= 3
thank you! so would the probability be .75?
If the probability to win is 3/7, what are the odds to win?
