Answer:
<u>The team building event will cost $24 for 4 attendees.</u>
Step-by-step explanation:
Given,
Cost charged corporate team building = $6 for every attendee
Number of attendees = 4
We will multiply the amount of one ticket with number of attendees in order to find the total cost.
Cost charged for 4 attendees = 6*4
Cost charged for 4 attendees = $24
nCr(20, 2) = 190 ways of selecting 2 from 20
nCr(10, 1) = 10 ways of selecting 1 from 10
To find the over all probability of winning,
Calculate the Harmonic Mean (19) and divide by 2
Equivalent to
1/ (1//190 + 1/10) =9.5
So the probability is 1/9.5 = 2/19.
The answer for that is the second one
