Question

Subparts a,b, and c were already solved. Just need D and E still. 

A spinner with equally sized slices labeled 1 to 8 is spun once. The number spun will be
recorded as the outcome. Consider the following events:
Event A: The number rolled is odd.
Event B: The number rolled is less than 4.
(a) Find P(A)
(b) Find P(B)
(c) Find P(A or B)
(d) Find P(A and B)
(e) Find P(BC) (The complement of event B)
Transcribed Image Text:A spinner with equally sized slices labeled 1 to 8 is spun once. The number spun will be recorded as the outcome. Consider the following events: Event A: The number rolled is odd. Event B: The number rolled is less than 4. (a) Find P(A) (b) Find P(B) (c) Find P(A or B) (d) Find P(A and B) (e) Find P(BC) (The complement of event B)
Expert Solution
Step 1

Probability = favourable outcometotal number of outcomes

Event A = number rolled is odd

Event B = number rolled is less than 4

n(A) = {1,3,5,7} = 4

n(B) = {1,2,3} = 3

n(Bc) = {4,5,6,7,8} = 5

sample space = {1,2,3,4,5,6,7,8}

n(S) = 8
