Ateacher asks each student to randomly choose a number from 1 to 90 and write it down. keiko and mitsugu write down the number. what is the probability that both of their choices will be greater than 75? express your answer as a decimal. if necessary round your answer to the nearest thousandth. a. 0.028 b. 0.167 c. 0.972 d. 0.026

A. 0.028

Step-by-step explanation:

Given,

The total numbers = 90 ( from 1 to 90 ),

Also, numbers greater than 75 = 90 - 75 = 15,

Keiko and Mitsugu write down numbers randomly from these numbers,

Hence, the probability that both of their choices will be greater than 75

= The probability of a number greater than 75 × the probability of a number greater than 75

=

=

= 0.027777

≈ 0.028
