Question

A jar contains four balls, numbered from one to four. You randomly pick a ball. It is numbered one or four.find the probability

Answer 1

ok

Probability that the ball is numbered 1 = 1/4

Probability that the ball is numbered 4 = 1/4

Probability that the ball is numbered 1 or 4 = 1/4 + 1/4

= 2/4

= 1/2

b)

Probability that the bottle be orange = 5/12

Probability that the botthe be warm = 6/12 = 3/6 = 1/2

Probability that the bottle be orange flavor or warm = 5/12 + 6/12

= 11/12
