the formula to find the probability is p(a ∩ b)=p(b | a)p(a) and p(a ∩ b) = .
total numbers in the hat = 30
let a be the event of picking number 1 and b be the event of picking number 2 then without replacement.
clearly, the probability of the second event depends on the first event.
so, p(a ∩ b)=p(b | a)p(a)
p(b | a) means probability of event b with the condition that event a has happened.
so, the first number picked is 1.
therefore, p(b | a) =
p(a ∩ b)=
answer: the answer is 50%
88.98 i did so much math to figure this out so im sorry i cant show my work
it takes 3 x 1/3 to make 1 cup so 3 cups = 9, 1/3 portions
