Probability

All the possibilities of two tosses are:

H - H

H - T

T - H

T - T

Probabilities:

no Heads . . . 0.25

no Tails . . . . . 0.25

one Heads . . . 0.5

one Tails . . . . . 0.5

two Heads . . . 0.25

two Tails . . . . . 0.25

at least one Heads . . . 0.75

at least one Tails . . . . . 0.75

the two results are the same . . . 0.5

the two results are different . . . 0.5

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
