Answer:
75%
Step-by-step explanation:
It's right
It would be 1/7 chance cause there are 7 people total but you have the 1 chance that you are going to get your own name
The answer is 62/95. You determine this by calculating the probability of both students being girls.
Probability first student is girl: 12/20
Probability second student is girl: 11/19
Multiply 12/20 * 11/19 = 132/380 or 0.347
Probability of both students not being girls: 1 - 0.347 = 0.653 or 62/95
X = 2
18 / 3 = 2
2 * 6 = 6
6 + 6 + 6 = 18
Hope this helps.
