Question

4. A die is rolled. Find t
is rolled. Find the probability of getting:
a b. a multiple of 3. c. a multiple of 4.
a number which is not a prime number.
e. a composite number.​

Answer 1

Answer:

a. 1/3

b. 1/6

c. 1/2

d. 1/2

Step-by-step explanation:

all possible outcomes = 1, 2, 3, 4, 5, 6

probability = total number of desired outcomes / total number of outcomes

a. E =  a multiple of 3

desired outcomes = 3,6

P ( E ) = 2 /6 = 1/3

b. E = a multiple of 4

desired outcomes = 4

P (E) = 1/6

c. E = a number that is not a prime number

desired outcomes = 1 , 4, 6

P(E) = 3/6 = 1/2

d. E = a composite number

desired outcomes = 1, 4, 6

P(E) = 3/6 = 1/2
