There are three different colored M&Ms-- Red, green and white. The probability of selecting a red M&M is 2/5, and the probability of selecting a green M&M is 1/4, so what is the probability of selecting a white M&M?

7/20

Step-by-step explanation:

Let the total probability be 1;

Given

Probability of selecting a red M&M = 2/5,

Probability of selecting a green M&M = 1/4

Required

Probability of selecting a white M&M

Probability of selecting a white M&M = 1 - (2/5+1/4)

Probability of selecting a green M&M = 1 - (4(2)+5(1)/20)

Probability of selecting a green M&M = 1 - (8+5/20)

Probability of selecting a green M&M  = 1 - 13/20

Probability of selecting a green M&M  = 7/20

hence the Probability of selecting a green M&M is 7/20

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
