As we must choose two speakers from a group of six.
From the question, n = 4 and r = 2. On substituting
What is combination?
Combination is the process of choosing elements from a collection of elements where the order of the selections is irrelevant. A selection procedure is called a permutation if one of its criteria is the order in which candidates are chosen. The order is irrelevant in combination, a special kind of permutation selection. As a result, there are always more permutations than combinations when choosing 'k' items from 'n' elements.

Is there a list of choices that goes along with the question,
that you neglected to share ?
There are millions of expressions that are equivalent to 16a + 24 B .
One of them is:
<em>8 (2a + 3 B)</em> .
Answer:
The correct option is;
C. 15 in 16
Step-by-step explanation:
The given information are;
The number of press-ups required = 14 press-ups
The number of press-ups Jessica is sure to do = 10 press-ups
The chance of Jessica doing subsequent press-ups after 10 halves each time
The consequence of not completing the 14 press-ups = Punishment
The probability that Jessica does goes on to do 11 press-ups = 1/2
The probability that Jessica does goes on to do 12 press-ups = 1/2×1/2
The probability that Jessica does goes on to do 13 press-ups = 1/2×1/2×1/2
The probability that Jessica does goes on to do (completes) 14 press-ups = 1/2×1/2×1/2×1/2 = 1/16
Therefore;
Since the probability that Jessica does not receive a punishment because she completed the 14 push-ups is 1/16, we have;
The probability that Jessica does not complete the 14 press-ups and receives a punishment = 1 - 1/16 = 15/16 which is 15 times out of 16 or 15 in 16.
