Question

Give a test to a group of students the grades and gender are summarized below if one student is chosen at random find the property ability that the student was female or got AB round the solution of 3 decimal places

Answer 1

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

Data Table

Step 02:

probability (female) or probability (B)

probability = favorable outcomes / total outcomes

probability (female) = 32 / 55

probability (B) = 8 / 55

probability (female) or probability (B) = (32 / 55) + (8 / 55) - (32/55)*(8/55) = 0.6426

The answer is:

probability (female) or probability (B) = 0.643
