Answer: 0.14

=======================================================

Step-by-step explanation:

There are

  • 5 students who got an A
  • 35 students total

We divide these two values to get the probability we want

5/35 = 1/7 = 0.142857 which is approximate

This rounds to 0.14 when rounding to the nearest hundredth.

There's about a 14% chance of randomly selecting someone who got an A.
