Answer:
55% or 0.55(as a decimal)
Step-by-step explanation:
40% of their clients buy auto insurance policies = P(A)
30% of their clients buy home insurance policies = P(H)
15% of their clients buy both home and auto insurance policies = P( A ∩ H)
The probability a randomly selected client buys a home or auto insurance policy = P (A ∪ H) is calculated as
P ( A ∪ H) = P(A ) + P ( H ) - P( A ∩ H)
= 40% + 30% - 15 %
= 70% - 15%
= 55%
Therefore, the probability that a randomly selected client buys a home or auto insurance policy is 55% or expressed as decimal = 0.55
Answer: D
You can still simplify 9/15
9/15 can be divided by 3, thus the answer will be 3/5.

<u>Step-by-step explanation:</u>
Here we have , ab= 8 & a^2+b^2=16 i.e. and .
We need to find value of (a+b)^2 i.e. 
:
It's and identity and we know that
