Question

Mila spins two spinners. One spinner has two equal sections labeled 1

and 2. The other spinner has three equal sections labeled 1, 2, and 3.
What is the probability that the sum of the two spins is 4?

Answer 1

`(1)/(2) * (1)/(3) + (1)/(2) * (1)/(3) = (1)/(3)`

Explanation:

1st case :

1+3= 4

2nd case:

2+2=4

For that , we add the probability of the 2 cases to get

1/3

Answer 2

• The probability that the sum of the two spins is 4 is 1/3 or 33.33%

--------------------

Total number of outcomes is:

• 2*3 = 6

Outcomes with the sum of 4:

• 1 + 3 = 4 and 2 + 2 = 4

So we have two favorable outcomes out of six total outcomes.

The probability that the sum of the two spins is 4:

• P = favorable ourcomes / total outcomes
• P(4) = 2/6 = 1/3 or 33.33%
