Acoin is flipped five times. find the number of possible sets of heads and tails that have 2 heads. a. 0 b. 1 c. 5 d. 10 select the best answer from the choices provided a b c d

option d

Step-by-step explanation:

Given that a coin is tossed 5 times. Assuming it is a fair coin, head and tail are equally likely.

If we toss 5 times, the number of heads can be either 0 or 1 or 2...5.

Number of outcomes that have 2 heads

=out of 5, two heads and three tails

=5C2

=5(4)/2

=10

So answeris 10

Option d is right answer

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
