Answer:
Step-by-step explanation:
Given
P(A or B)= P(B)-P(A and B)
P(A)=1/3
P(A and B)=1/8
P(A or B)= 3/4
Required
Find P(B)
To find P(B), all we need to do is to substitute values of P(A or B) and P(A and B) in the given equation.
This goes thus;
P(A or B) = P(B) - P(A and B) becomes
Make P(B) the subject of formula
Take L.C.M
Add fractions
From the workings above, the value of P(B) using the given equation is
Answer: d
Step-by-step explanation:
The answer is A
B is wring because the parenthesis change the answer
C is wrong because its adds and then multiplies g which gives different answers
D is wrong because you would need to multiply e by two in the second part to be equivalent
