Answer:
P(7∩Q) = P(7) × P(Q)
Option 4: P(7∩Q) = P(7) × P(Q)
Step-by-step explanation:
P(7∩Q) represents the probability of choosing the secret code "7Q".
If A and B are independent events, then,
P(A∩B) = P(A) × P(B)
Let A be the event of choosing a number from 0-9 and
B be the event of choosing an alphabet.
Clearly, A and B are independent.
Therefore,
5
the answer is 5.75, but when rounded off, it will become 5
A. 10%
First calculate how much percentage is in one dollar, which is 5% per dollar, then times that by how much money is deducted which is $2, and you will get your answer 10%.
Hope this helps good luck!
How to do the estimation
He can use the probability of how many people chose English and multiply by 9.7 since there are 970 people / 100 people who asked = 9.7
