Question

The probability of winning a game is 25% . How many times should you expect to win if you play 36 times ?

1. 3 times
2. 7 times
3. 9 times
4. 11 times

Answer 1

The answer is 9 times. If u struggle w probability like I do u can do it a different way w/our decimals. (Only works for 25,50 and 75%). U can take 25 and know it’s 1/4 of one hundred. U take the 4 and divide. 36/4 = 9. This way is easier for me but if I like the decimal way the. Go for it. My mind works in mysterious ways. ;)

Answer 2

25% of 36 = 0.25 x 36 = 9

Answer: 9 times
