There are 10 students in a class: 6 boys and 4 girls. if the teacher picks a group of 3 at random, what is the probability that everyone in the group is a boy?

.

Step-by-step explanation:

It is given that,

Total number of students = 10

Number of boys = 6

Number of girls = 4

Total number of ways to select 3 students from 10 students.

Total number of ways to select 3 students from 6 boys.

The probability that everyone in the group is a boy is

Therefore, the required probability is 1/6.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
