Using The Probabilities Given Find The Probability That A Student Earns A Grade Of A Enter Number In Decimal Form Rounded To The Nearest Hundredth class=

Sagot :

Answer:

0.14

Step-by-step explanation:

Here, we want to find the probability that a student earns the grade of A

Mathematically, we have this as the frequency of A divided by the sum of all frequencies

From the question, the sum of all frequencies will be (5 + 10 + 15+ 3 +2) = 35

Now we place the frequency of A over this

This gives;

5/35 = 1/7 = 0.14
