The purple balls constitute 1/3 of the amount of balls there, so you’re that likely to pluck one out.
You are adding by 5 in the sequence.
If f(1) is -7
f(2) = -2
f(3)= 3
f(4)=8
f(5)=13
f(6)=18
Therefore, f(7)=23
The probability that Boris will win the contest is:
P = 0.286
<h3>
How to get the probability?</h3>
For some given odds a:b, the probability is just computed as the quotient between a and b, which gives:
P = a/b
In this case, the odds are 2:7, so the probability that Boris will win the contest is:
P = 2/7 = 0.286
Written in percentage form, we get:
P = 28.6%

You need to divide 2/5 and 3/4. First, you need to do "Keep Change Flip". We do this by keeping 2/5 the same, changing the division sign to a multiplication sign and flipping 3/4 to make 4/3. Lastly, you add them up and get your answer.
2/5 ÷ 3/4
2/5 X 4/3 = 8/15
