If a certain coin is flipped, the probability that the coin will land heads is 1/2. If the coin is flipped 5 times, what is the probability that it will land heads up on the first 3 flips and not on the last 2 flips?

A. 3/5 B. 1/2 C. 1/5 D. 1/8 E. 1/32
We want P(heads on 1st AND heads on 2nd AND heads on 3rd AND tails on 4th AND tails on 5th) = P(heads on 1st) x P(heads on 2nd) x P(heads on 3rd) x P(tails on 4th) x P(tails on 5th) = 1/2 x 1/2 x 1/2 x 1/2 x 1/2 = 1/32

Given that If a certain coin is flipped, the probability that the coin will land heads is 1/2. If the coin is flipped 5 times, and we need to find what is the probability that it will land heads up on the first 3 flips and not on the last 2 flips?
Coin is tossed 5 times => Total number of cases = \(2^5\) = 32
We need to get head in the first 3 flips and not in the last 2 flips => HHHTT
So, there is only one case out of 32 when this will happen.
=> P(HHHTT) = \(\frac{1}{32}\)
So, Answer will be E Hope it helps!
