They can be chosen in 12,444 ways.

There are three different scenarios that have more boys being chosen than girls:
5 boys and 0 girls
4 boys and 1 girl
3 boys and 2 girls

We will set up combinations for all 3 of these scenarios:
(_{18}C_5\times{_{19}C_0)+(_{18}C_4\times_{19}C_1)+(_{18}C_3\times_{19}C_2)
\frac{18!}{5!13!}\times \frac{19!}{0!19!}+\frac{18!}{4!14!}\times \frac{19!}{1!18!}+\frac{18!}{3!15!}\times \frac{19!}{2!17!}
\\
\\=8568+3060+816=12444

1) The probability of rolling a 1 is 10/40 and the probability of rolling a 5 is 6/40. Add these together to get 16/40 which simplifies to 2/5 probability of rolling a 1 or 5.

2) The probability of the spinner landing on section 2 is 36/80 which simplifies to 9/20

3) To find the relative frequency, divide each number by the total number of trials. In this case we're only look at the clubs so divide 8/40, which is 0.2 or 20%

4) There were 60 trials total and since we're finding the relative frequency of red, divide 13/60 which is 0.216 rounded to 0.22 or 22%

5) The spinner is spun 84 times and it lands on A 14 times so the probability of it landing on A is 14/84 which simplifies to 1/6 or 0.166 rounded to 0.17 or 17%

I hope this helps you!

Gerald ran out of tail on his patio. The width of the remaining area is 2 2/9 feet. the length of the remaining area is 7 feet.
tamaranim1 [39]
How much left is the simply the area.

Area = length * width

Area = 7 feet * 2  2/9

Area = 7 * 20/9 = 140/9

Area = 140/9  square feet.
