A snack-size bag of M&Ms candies contains 14 red candies, 10 blue, 5 green, 11 brown, 3 orange, and 12 yellow. If a candy is

Nitella [24]

Answer:

The odds of getting a green M&M is $\frac{1}{10}$ and the probability of getting a green M&M is $\frac{1}{11}$

Step-by-step explanation:

Red candies = 14

Blue candies = 10

Green candies = 5

Brown candies = 11

Orange candies = 3

Yellow candies = 12

Total No. of candies = 14+10+5+11+3+12 = 55

(a) the odds of getting a green M&M

Green candies = 5

Total number of candies excluding green or unfavorable = 50

Odds of getting a green M&M = $\frac{\text{favorable outcome}}{\text{Unfavorable outcomes}}$

= $\frac{5}{50}$

= $\frac{1}{10}$

(b) the probability of getting a green M&M

Green candies = 5

Total No. of candies = 55

So, the probability of getting a green M&M = $\frac{5}{55}$

= $\frac{1}{11}$

Hence the odds of getting a green M&M is $\frac{1}{10}$ and the probability of getting a green M&M is $\frac{1}{11}$

nydimaria [60]

Answer:

1. $66

2. 30 + 4r

Step-by-step explanation:

Let

Price of admission into the park=$30

Price of every ride in the park=$4

Number of rides =x

Total cost of going to the park= 30+4x

1. How much money would Claire have to pay in total if she goes on 9 rides

Total cost of going to the park= 30+4x

When x=9

=30+4x

= 30 + 4(9)

=30 + 36

=$66

2. How much would she have to pay if she goes on r rides?

When x=r

Total cost of going to the park= 30+4x

= 30 + 4(r)

=30 + 4r
