Step-by-step explanation:
Given that Nuri joins a game for a car. The rule is that Nuri pick one key from box either A, B, or C. A box has two keys but only one can be used. B box has three keys but only one can be used. C box has two keys but none of them can be used.
Each box is equally likely to be selected.
In other words
If A is selected then probability of winning is using the correct key out of two keys i.e. 0.5
If B is selected then probability of winning is using the correct key out of three keys i.e. 0.333
If c is selected then probability of winning is using the correct key out of two keys i.e. 0.00
So the probability that Nuri can win the car
=
Answer:
The required inequalities are and
.
Step-by-step explanation:
Consider the provided information.
Daniel moves no more than 30 of his sheep and goats into another field.
Let s represent the number of sheep and g represent the number of goats.
No more than means the number of sheep and goats should be less than or equal to 30.
For less than or equal to use the inequality ≤
Hence the required inequality is:
More than 7 of his animals are sheep.
This can be represented as:
Hence, the required inequalities are and
