Q:

Use the spinner to find each theoretical probabilityP (a number no more than 5) P (an even number) P (a number less than 3)

Accepted Solution

A:
Here is your answer

1) 5/8

2) 1/2

3) 1/4

REASON:

P(event)=

Favourable outcomes/Possible outcomes

All possible outcomes are:

1,2,3,4,5,6,7 and 8

No. of possible outcomes= 8

1] Number no more than 5 are:

1,2,3,4 and 5

Favourable outcomes=5

P(a number no more than 5)=5/8

2] All even numbers are:

2,4,6 and 8

Favourable outcomes=4

P(an even number)= 4/8=1/2

3] Numbers less than 3 are:

1 and 2

Favourable outcomes= 2

P(a number less than 3)= 2/8=1/4

[Note:- No more than 5 means a number which is not greater than 5,i.e. 5 must be included]
