A six sided die and a standard nickel are tossed. What is the probability that the number of dots on the upper face of the die is a prime number and the nickel lands heads facing up?

Probability of head and prime = 1/4 or 0.25

Step-by-step explanation:

Total number face in dice = 6

Face that is prime ( 2,3,5) = 3

Total number face in nickel = 2

Total number of head in nickel = 1

Probabilty of prime = 3/6

Probabilty of prime = 1/2

Probabilty of head = 1/2

Probability of head and prime

= 1/2 * 1/2

= 1/4

= 0.25

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
