A spinner has two sections of equal size that are numbered 2 and 4. The spinner will be spun three times.
What is the probability that the sum of the three spins is 10?
6/8
3/8
1/8
Answers
Given:
Section one of spinner = 2
Section two of spinner = 4
Number of spins = 3
To Find:
Probability that the sum of three spins is 10
Solution:
The possible outcomes of two spinners is -
2 = 2 2 2 , 2 2 4, 2 4 2, 2, 4 4
4 = 4 4 2 4 2 4 4 2 2 4 4 4
Total combinations = 8
Possible three spins outcome = 244, 442 and 424
Thus,
The probability of a sum of a 10 = 3 / 8
Answer: Probability that the sum of three spins is 10 is 3/8.
Given : A spinner has two sections of equal size that are numbered 2 and 4. The spinner will be spun three times.
To find : probability that the sum of the three spins is 10
Solution:
A spinner has two sections of equal size that are numbered 2 and 4
Possible outcome = 2
The spinner will be spun three times.
hence total possible outcomes = 2 * 2 * 2 = 8
=> n(S) = 8
S = {222 , 224 , 242 , 244 , 422 , 424 , 442 , 444}
sum of the three spins is 10
4 + 4 + 2 = 10
Hence there has to be 2 once
2 once = ³C₁ = 3 Times or 4 Twice = ³C₂ = 3
n(E) = 3
E = { 244 , 424 , 442 }
Hence probability = n(E)/n(S)
= 3/8
3/8 is the probability that the sum of the three spins is 10
