Step-by-step explanation:
We define two events for this case A and B. And we know the probability for each individual event given by the problem:
And we want to find the probability that A and B both occurs if A and B are independent events, who menas the following conditions:
And for this special case we want to find this probability:
And we can use the following formula:
And replacing the info we got:
Ok. So what I did was I chose a number that would be easy to manipulate The number I chose was 10, I then multiplied it by 4 to get 40, then subtracted 3 to get 37 - that was the first part of the question. The second part wanted me to take the same number, multiply it by 3 and then add 7. So 10 multiplied by 3 is of course 30 and then you just add 7 to get 37. Hey look! Its a match! I hope this helps.
