a=8:12 c=£1.05:0.70 d=30:50:60:40
b=9:15
Step-by-step explanation:
Using the concept of probability and the combination formula, it is found that there is a 0.4444 = 44.44% probability they get to be on the same team.
--------------------
- A probability is the <u>number of desired outcomes divided by the number of total outcomes.</u>
- The order in which the children are chosen is not important, which means that the combination formula is used to find the number of outcomes.
--------------------
<u>Combination formula:
</u>
is the number of different combinations of<u> x objects from a set of n elements</u>, given by the following formula.
--------------------
Finding the number of desired outcomes:
- Andy and Ollie on the same team, plus 3 children from a set of 8.
- Can be on either team, blue or red, so multiplied by 2.
--------------------
Finding the number of total outcomes:
- <u>5 children from a set of 10</u>, thus:
--------------------
The probability is:
0.4444 = 44.44% probability they get to be on the same team.
