Question

Tristan has 3 bottles of water and 4 bottles of juice in his ice chest. What is the probability that he will reach into the chest and pull out two bottles of juice in a row if he does not replace the first one?All answers should be given as a fraction in simplest form!

Any help would be appreciated, Thanks!!!

Answer 1

Explanation:

P(j=1st) =4/7

P(j=2nd) =3/6

P(j two in a row) = (4/7)*(3/6)= 12/42 = 6/21 = 2/7

P(j two in a row) = 2/7
