Answer:
The probability of getting exactly 3 head=0.3125
Step-by-step explanation:
Given that probability of getting head p=0.5
So probability of getting tail q=0.5
Number of coin toss n=6
And number of trial r=3
We know that from Binomial distribution function,the probability given as follows
So now by putting the values
Now by solving this
The probability of getting exactly 3 head=0.3125
If 40% of the students are girls then that means 60% of the students are boys.
First, turn 60% into a decimal.
60% = 0.6
Second, divide by the number of boys.
36 / 0.6 = 60 total students
Third, turn 40% into a decimal.
40% = 0.4
Fourth, multiply by the total number of students.
60 * 0.4 = 24 girls
Best of Luck!
