Answer:
69/195
Step-by-step explanation:
So u add 24 and 16 to find the total number of people who are there
The total is 40
If they want at least 2 girls
So one of the probability for one girl is 24/40 which is 3/5
The other probability of another girl is 23/39
So u multiply 23/39 by 3/5 which is 69/195
Correct me if this is wrong
Sorry
Answer:
30.77%.
Step-by-step explanation:
There are a total of 40 members.
24 girls 16 boys.
Prob( 0 girls being chosen - so all boys ) = 16/40 * 15/39*14/38* 13/37*12/36 = 0.0063956
Prob( first one to be chosen is a girl then all boys) = (24/40*16/39*15/38*14/37*13/36) = 0.013276
There are 5 ways of 1 girl being chosen so
Prob(1 girl out of 5 chosen) = 0.013276 * 5 = 0.06638
Prob( First 2 chosen are girls then all boys) = 24/40 * 23/39 * 16/38*15/37*14/36
= 0.023489
Number of ways of 2 girls being chosen is 5C2 and so the probability of 2 girls
= 0.023489 * 5C2
= 0.023489 * 10
= 0.23489.
Required probability = 0.23489 + 0.06638 + 0.0063956.
= 0.3076656
= 30.77% to the nearest hundredth.
