Answer:
Hope it helped,
Happy homework/ study/ exam!
Alright.
So let's say the number of adults is x.
Therefore, the number of boys is 7x + 1.
And then the total amount of girls is 3.5x + 0.5
So then:
x + 7x + 1 + 3.5x + 0.5 = 82
11.5x + 1.5 = 82
11.5x = 80.5
x = 7
So now we can figure out the number of male and female students.
Male students = 7x + 1
7*7 + 1
49 + 1
50
Male Students = 50
Female students = half of 50
50/2 = 25
Female Students = 25

Answer:The right answer will be
0. 546875
Step-by-step explanation:
When 6 coins are tossed , the total number of outcomes is 2*2*2*2*2*2= 64
The number of ways of getting two heads are 6!/2!*4!=15.
The probability of getting two heads P(A) is 15/64 .
In the same way, the probability of getting three heads P( B) is 5/16.
Now, P(A)+P(B)= 0.546875
