Question

a spinner has 6 equal-sized sections numbered 1,1,2,2,3and 4. what is the sample space for the spinner, and what is the probability of spinning a 1?

Answer 1

Answer:

S={1, 1, 2, 2, 3, 4}

Probability of spinning a 1 = 1 in 3 or 33%

Step-by-step explanation:

The sample space is the set of all possible outcomes in an experiment. The outcomes here are the numbers in each section of the spinner: 1, 1, 2, 2, 3, 4. The sample space is:

S={1, 1, 2, 2, 3, 4}

Two out of six possible outcomes are "1s", therefore the probability of spinnin a 1 is:

$P(1)=\frac{2}{6}=\frac{1}{3}=33.33\%$

The probability of spinning a 1 is 1 in 3 or 33%.
