M&M plain candies come in various colors. According to the M&M/Mars Department of Consumer Affairs, the distribution of

colors for plain M&M candies is as follows.
Color Purple Yellow Red Orange Green Blue Brown
Percentage 21% 18% 18% 8% 8% 6% 21%

(a) Find P(green candy or blue candy).

Are these outcomes mutually exclusive? Why?
Yes. Choosing a green and blue M&M is possible.
No. Choosing a green and blue M&M is possible.
Yes. Choosing a green and blue M&M is not possible.
No. Choosing a green and blue M&M is not possible.


(b) Find P(yellow candy or red candy).

Are these outcomes mutually exclusive? Why?
Yes. Choosing a yellow and red M&M is possible.
Yes. Choosing a yellow and red M&M is not possible.
No. Choosing a yellow and red M&M is possible.

Since the Σ( of all colors )= 100%,  OR 1, then:

a) P(GREEN ∪ BLUEU) = P(G) + P(BL) = 8%+6% = 14% or 0.14

Since we have to choose ONE candy and only ONE candy at random, then tey are mutually exclusive: No. Choosing a green and blue M&M is possible

b) P(YELLOW ∪ RED) = P(Y) + P(R) = 18%+18% = 36% or 0.36
SAME ANSWER AS BEFORE: mutually exclusive

c) P(NOT PURPLE), Let's calculate 1st, the probability of having a PURPLE:
P(PURPLE) = 21% or 0.21
And the Probability of NOT having a PURPLE is 1-0.21 = 0.79

Answer:

The no. of possible handshakes takes place are 45.

Step-by-step explanation:

Given : There are 10 people in the party .

To Find: Assuming all 10 people at the party each shake hands with every other person (but not themselves, obviously) exactly once, how many handshakes take place?

Solution:

We are given that there are 10 people in the party

No. of people involved in one handshake = 2

To find the no. of possible handshakes between 10 people we will use combination over here

Formula : ^nC_r=\frac{n!}{r!(n-r)!}

n = 10

r= 2

Substitute the values in the formula

^{10}C_{2}=\frac{10!}{2!(10-2)!}

^{10}C_{2}=\frac{10!}{2!(8)!}

^{10}C_{2}=\frac{10 \times 9 \times 8!}{2!(8)!}

^{10}C_{2}=\frac{10 \times 9 }{2 \times 1}

^{10}C_{2}=45

No. of possible handshakes are 45

Hence The no. of possible handshakes takes place are 45.
