Answer:
This states that the probability of the occurrence of two independent events is the product of their individual probabilities. The probability of getting two heads on two coin tosses is 0.5 x 0.5 or 0.25.
Step-by-step explanation:
The probability of getting 2 heads with 2 coins can be broken into 2 steps:
The first coin must show Heads AND
the second coin must show Heads.
p(h,h)= P(H) <----- and means multiply
P(H) x P(H)= 1/2 x 1/2 =1/4
(2-a)^2 + 3(2-a)
A^2 -2a + 4 + 6 -3a
A^2 -5a +10
Answer:
15x+45-2x=15x-2x-10
13x+45=13x+10
13x-13x=10-45
if you simplify further
you will not get an answer there is a mistake in the question
Answer:
-1 is the only answer that is greater than -5
