Answer:

0.10

Step-by-step explanation:

hello,

there are 5 answers and 2 are correct

I choose a first answer - the probability to be a correct one is 2/5

then now, there are 4 left answers and only 1 left is correct

the probability to choose the correct one is 1/4

so in total the probability to choose the 2 correct answers out of 5 is

$\dfrac{2}{5}*\dfrac{1}{4}=\dfrac{1}{10}$

which is 0.10

hope this helps

Hector is dividing students into groups for an HR wants to divide the boys and girls so that each group has the same number of t

Roman55 [17]

Answer:

7 groups, 3 boys and 8 girls

Step-by-step explanation:

Let total number of groups be $x$

and total hikers in one group be $y$

if number of girls and boys in every group is same, then

$\frac{21}{x} + \frac{56}{x} = y$

$\frac{21 + 56}{x} = y\\x*y = 77$ ....(1)

from (1) $x$ will either be 11 or 7

for $x = 11$ the values won't be real.

For $x = 7\\y = \frac{77}{7} \\y = 11$

so there will be 7 groups with 11 hikers in each groups and every group will have $\frac{21}{7} = 3$ boys and $\frac{56}{7} = 8$ girls
