Try using fraction, i think the ans is 28/205 ;)
Answer:
0.00014
Step-by-step explanation:
The box contains a total of 24 + 33 + 35 = 92 jelly beans
If we need to pick 8 jelly beans and want them all to be green:
We can choose 8 green jelly beans from 33 green in C₃₃,₈ different ways
The total ways we can choose 8 jelly beans out from 92 is: C₉₂,₈
Thus, the probability we're looking for is C₃₃,₈ / C₉₂,₈ = 13884156/93080887185 =0.00014
To find the probability of not having twins, we can subtract the probability of having twins from 1. This is because probabilities always add up to 1.
1 - 0.015 = 0.985
The probability of not having twins is 0.985.
Hope this helps!! :)
