Answer:

Yes, they are mutually exclusive
Step-by-step explanation:
Given
Refer to the table in the question
Solving (a): P(green candy or blue candy)
This is calculated as:

From the question:


So:



Convert to decimal

Solving (b): Are they mutually exclusive?
Multiple events A and B are mutually exclusive if;

In (a) above:

and this is so every other possible colour of candy
e.g.

Hence:
The events are mutually exclusive
Answer:
P(X >= 86) = P (Z >= 1) = 0.1587 from the Z-scores table
Step-by-step explanation:
Hopefully this time I will not make an algebraic mistake.
Ok
so mean u = 79, and standard dev = s = 7
We want P(X >= 86)
Standardize:
P ( (X - u)/s >= (86 - 79)/7 ) = P (Z >= 1) = 0.1587 from the Z-scores table
