The percent of students in the sample who were male is 48%.
Step-by-step explanation:
The complete question is:
Researchers once surveyed 100 students on which superpower they would most like to have. The following two-way table displays data for the sample of students who responded to the survey.
Superpower Male Female TOTAL
Fly 26 12 38
Invisibility 12 32 44
Other 10 8 18
TOTAL 48 52 100
What percent of students in the sample were male?
Solution:
The probability of an event <em>E</em> is the ratio of the number of favorable outcomes to the total number of outcomes.
The number of males in the sample is, <em>n</em> (M) = 48.
Total number of students, <em>N</em> = 100.
Compute the probability of selecting a male student as follows:
Then the percent of students in the sample who were male is:
Thus, the percent of students in the sample who were male is 48%.
