I think it’s 1 because there’s 9 shirts left and atleast one of them has to be green
3/10 + 45/100
= 30/100 + 45/100
= 75/100
Answer:
That is a 25% change.
Step-by-step explanation:
7 yellow, 5 green, 3 blue...total of 15
P(yellow party hat) = 7/15
do not replace
P(yellow hat) = 6/14
P(both) = 7/15 * 6/14 = 42/210 which reduces to 1/5 or 0.2 or 20%
