Heads lands 3 times and tales lands 5 times in 8 coin flips
Step-by-step explanation:
A compound event is one in which the probability of more than one outcome or event to have occurred at the same time is sought. The probability of a compound event is the sum of the probabilities of the individual events less the probabilities already captured in both event probabilities
Answering compound event questions can be done by the use of a tabular or diagram format.
Therefore, the compound event in the list is heads lands 3 times and tales lands 5 times in 8 coin flips.
The answer will be the biggest number, by which you can divide both 28 and 32. So you can divide them in 4 groups (28/4=7 girls per group & 32/4=8boys per group)
If she wants to only use 85 a month then doing the math it would be 85-65=20 divided by 5 equals 4 so she would get 4 gigabytes while staying within her budget :)
