Answer:
The probability that the counter was blue is 
Step-by-step explanation:
Number of black Counters = 5
Number of blue Counters = 4
Number of white Counters = 1
We need to write down the probability that the counter was blue.
First find Total Counters
Total Counters = Number of black Counters + Number of blue Counters + Number of white Counters
Total Counters = 5+4+1
Total Counters = 10
Now, we need to find probability that the counter taken was blue
The formula used is:

There are 4 blue counters in the back, so Favourable outcomes = 4

The probability that the counter was blue is 
Answer:

Step-by-step explanation:
To write this equation with h isolated, we cancel everything else on the right hand side of the equals sign. This means we cancel π and r².
Since both of these are attached to h by multiplication, we divide by both to cancel. We can divide by both at the same time:

Answer:
Find what <u>both fractions</u> are <u>divisible</u> by.
Step-by-step explanation:
Take
and if needed, use a multiplication tabel to help you figure out what both numbers are divisible by. 5 and 15 are both divisible by 5. Now you can reduce the answer to
.
