This figure has 5 faces if you count all the sides of the shade
Answer:
53.57%
Step-by-step explanation:
We have to calculate first the specific number of events that interest us, if at least 3 are girls, they mean that 2 are boys, therefore we must find the combinations of 3 girls of 5 and 2 boys of 3, and multiply that, so :
# of ways to succeed = 5C3 * 3C2 = 5! / (3! * (5-3)!) * 3! / (2! * (3-2)!)
= 10 * 3 = 30
That is, there are 30 favorable cases, now we must calculate the total number of options, which would be the combination of 5 people from the group of 8.
# of random groups of 5 = 8C5 = 8! / (5! * (8-5)!) = 56
That is to say, in total there are 56 ways, the probability would be the quotient of these two numbers like this:
P (3 girls and 2 boys) = 30/56 = 0.5357
Which means that the probability is 53.57%
Ok, 65% of the attendants were men, 25% were women.
That leaves us with 10% remaining.
From those 10% .................The problem tells us that 40% are boys
So 10% * ( 0.4 ) = 4% ..............This means that 4% of the total attendants were boys.
So the distribution is
65%........men
25%........women
4%..........boys
6%...........girls
640 boys attended the game.....> this means that 4% of the total amount of people is 640.
So the number of persons that attended were
T= 100% *(640)) / 4% = 16000 people
