The number of guests that were at the party is 26. This was illustrated in the probability.
<h3>How to compute the probability?</h3>
From the information, it was stated that twenty six soft-drinks were consumed. Therefore, it implies that there were 26 people.
From the information, 9 guests had raspberry and 13 had cola while the remaining was shared equally. Therefore, the raspberry consumed will be 11 and 15 cola were drank.
The probability that a randomly chosen party guest had a cola drink will be:
= 15/26
The probability that a randomly chosen party guest had a raspberry drink will be:
= 11/26
The probability of the people who had both a raspberry and cola drink will be 0 since everyone had different drinks.
