Question

PLEASE HELP ME Every day, Navya's teacher randomly picks a number from 1 to 100 to be the number of the day. The

number of the day can be repeated. There are 180 days in the school year. Predict how many days the
number of the day will be greater than 25.
The number of days in which a number chosen is greater than 25 is

Answer 1

135 of the random selections would be numbers greater than 25.

Explanation:

Since 25 is 25% of 100, that means that 75% of the random selections would be over 25.

75% = 0.75

180*0.75 = 135

135 of the random selections would be numbers greater than 25.

Answer 2

135 days

Explanation:

There are 100 numbers

There are 75 numbers greater than 25 (26-100)

P(number greater than 25) =

= number of numbers greater than 100/ total outcomes

= 75/100

=3/4

There are 180 days, so multiply the number of days by the probability

3/4*180 =135
