P = Number of favourable outcomes ÷ Sum of total outcomes
So, Probability of drawing a blue sock is
Number of blue socks ÷ Number of total socks
= 6 ÷ 20
= 3 ÷ 10
= 0.3
Now as we have drawn a sock already the total number of socks in the drawer are 19
So, the probability of drawing a blue sock now will be :
= 6 ÷ 19
= 0.31

Hi there!
The total cost for a adults can be determined by multiplying the total amount of adults by the price per adult.
Price per adult = $3.50
Amount of adults = a
Total cost = 3.5a
The total cost for c children can be determined by multiplying the total amount of children by the price per child.
Price per adult = $2
Amount of adults = c
Total cost = 2c
The total cost for parents and children is
3.5a + 2c
The total cost for a family (2 adults and 3 children) can be found by plugging in 2 for 'a' and 3 for 'c'.
Therefore, we get the following:
Total cost = 3.5 × 2 + 2 × 3 = 7 + 6 = 13
Hence, the answer is $13
~ Hope this helps you.
