The probability of the first pick to be a boy is 10/25.
Let S be the sample space and E be the event of selecting 1 girl and 2 boys.
n(S)=number of ways selecting students of 25.
=²⁵C₃
=25·24·23/3·2·1
=2300
n(E)=(¹⁰C₁·¹⁵C₂)
=[10·(15·14)/2·1
=10500
P(E)=n(E)/n(S)=1050/2300=21/46
Answer:
4 x 3 x n + 4 = 4 x n + 64

did u want me to solve it too?
Answer:
Step-by-step explanation:
The recursive formula given is:
Generally a recursive formula is given as:
where a = first term
d = common difference
This implies that:
a = 5
d = -4
A general formula for an arithmetic sequence is:
Therefore, the general formula for the sequence is:
