Answer:
0.375, 0.125, 0.5
Step-by-step explanation:
given that you are taking a T/F exam and you have no idea at all about the answers to the last three questions.
Probability for correct guess = 0.5 remains constant for each of the three questions
X - no of questions is binomial with n =3 and p = 0.5
1) the probability that you guessed right on exactly one of the three questions
= P(X=1)
= 
2) the probability that you guessed right on zero of the three questions
= 
3) the probability that you guessed right on at least two of the questions
=

Step-by-step explanation:
Answer:
y + b > 15
Step-by-step explanation:
given data
positive integers = x, y, a, b
x divided by y then remainder = 6
a divided by b then remainder = 9
to find out
possible value for y + b
solution
we know that here when x divided by y then remainder is 6
its mean y is greater than 6 and when a divided by b then remainder is 9
so its mean b is greater than 9
and we know remainder is less than divisor
so here y + b must be greater than = 6 + 9
y + b > 15
Both sides would be the same, so set them to equal ans solve for x.
3x+4 = 2x +7
Subtract 4 from each side:
3x = 2x +3
Subtract 2x from each side:
x = 3
The answer is X = 3.
