Short Answers
P(Both) = 0.1792
Givens
The total number of roles = 100
Total number of heads = 56
Number of times rolled a four =  32 [check this for me].

Set up the probabilities.
P(H) = 56/100
P(4) = 32/100
P(H)*P(4) = P(Both)

Substitute and solve
P(Both) = 56/100 * 32/100 = 1792/10000
P(Both) = 112/625 because there are many cancellations. Or you could just express it as 0.1972

The probability that a student uses the Internet, given that he or she is in eighth grade is 8/13 or 0.66

<u>Step-by-step explanation:</u>

<u>From the table shown:</u>

  • The students in the eighth grade = 13
  • The eighth grade students using internet = 8

P(student uses the Internet in eighth grade) = P(eighth grade students using internet) / P(total students in the eighth grade)

⇒ 8/13

⇒ 0.66
