What the the probability of getting 2 heads when two coins are flipped 5 times?

18

Step-by-step explanation:

The probability of this event is 424=1/4. Then the probability of 5th toss is head is 1/2. Hence, in the end the answer is 14⋅12=18.

50%

Step-by-step explanation:

  O               O

   ^                ^         X5

(H) (T)        (H) (T)

The probability will always be 50% due to their only being 2 sides.

It will only be, IT WILL land on heads, or its NOT.

a is the correct

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
