Answer:
16.5 year
Step-by-step explanation:
Using, mean = sum/no. *of observations
Here,
=> 16.2 = (sum of ages of boys)/18
=> 16.2 x 18 = sum of ages of boys
=> 291.6 = sum of ages of boys
Similarly, sum of ages of girls = 27 x 16.7 = 450.9
Mean(total) = (sumof agesof boys + girls)/45
Mean = (291.6 + 450.9)/45 = 16.5

Step-by-step explanation:
Given that a card is drawn from a regular deck of 52 cards and is then put back in the deck. A second card is drawn.
Since here we have the draws with replacement we can say each trial is independent of the other.
i.e. the first card does not affect the second card at all.
the probability that:
a) The first card is red.
=
(b) The second card is hearts given that the first is red.
=P(second is hearts)
= 0.25
(c) The first card is red and the second is hearts.
= 
(since independent)
2+2 is 4
after that what u wrote i couldn't understand
