Answer:
31
Step-by-step explanation:
First of,
or, in probability is subtraction and not means you shouldn't use green (therefore leaving you with yellow and red)
Red = 42
Yellow = 20
P(Yellow or Not Green) = 
⁘ 
= 
Hence, 31
Answer:
M=(9, 13.5)
Step-by-step explanation:
What you do is you need to use the midpoint formula.
(x_1+x_2/2), (y_1+y_2/2).
(11, 13) and (7, 14) are your points and you put those numbers into the equation.
11 and 7 are x and 13 and 14 are y.
(11+7/2), (13+14/2)
M=(9, 13.5) is your answer.
In Binomial distribution, the expected value or mean is given by,
E(X) = np
where, p = probability of success and n=number of sample size.
E(X) = 100×0.4 = 40
