Question

Sifu has 6 girls and 8 boys in his karate class. He randomly selects one student

to demonstrate a self-defense technique. Find the probability of each event

Answer 1

42.86%

Explanation:

Event = Girl

Therare 6 girls and 8 boys, which are thus 6+8 =14 students in total and thus there are 14 possible out comes.

# of possible outcomes = 14

There are 6 girls in the class and thus there are 6 favorable outcomes.

# of favorable outcomes = 6

The probability is the number of favorable outcomes divided by the number of possible outcomes.

P(Girl) = # of favorable outcomes

# of possible outcomes

=
`(6)/(14)`

=
`(3)/(7)`

≈ 0.4286

= 42.86%

Result

`(3)/(7)` ≈ 0.4286 = 42.86%
