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
=
4.75×6=28.5
6 cookies= 6x
The expression is 6x+28.5
Multiplying decimals is the same as multiplying whole numbers except for the placement of the decimal point in the answer. When you multiply decimals, the decimal point is placed in the product so that the number of decimal places in the product is the sum of the decimal places in the factors.
