Question

Jason tossed a fair coin 3 times. What is the probability of getting a head and two tails in any order?

A)3 / 8
B)4 / 8
C)5 / 8
D)6 / 8

Answer 1

B

Answer 2

you would do 1/2*1/2*1/2 right because the theoretical probability of getting heads or tails is 1/2 and since he flipped it 3 times thats why you did 1/2^3

Answer 3

but thats not an answer choice

Answer 10

there are 8 possible outcomes when you toss a coin 3 times
8 is not such a big number that you cannot list them all

Answer 11

@tmm9772 are you saying B because 4 and 8 are equivalent?
