Can anyone help mewith this probability question.
Brrunno [24]

Answer:

It's 0.72

Step-by-step explanation:

It's independent of gender, so we can ignore the boys and girls part.

Adding the columns, 18 pass and 7 failed the last history test.

Adding those two numbers, you get 25.

So, 25 people took the test, and 18 passed.

You can get the probability by dividing 18 by 25.

Dividing that gives us 0.72
