Here we have selected positive numbers from 2 to 18 so there are total 17 numbers with us.
Now the prime numbers between 2 and 17 are
2, 3, 5, 7, 11, 13, 17
So there are 7 prime numbers between 2 to 18
We have to find the probability of selecting prime numbers between 2 to 18
Probability = Outcomes of interest / All possible outcomes
Probability prime = 7/17
Probability prime = 0.4117
So probability of getting prime number is 0.4117

Step-by-step explanation:
Do the FOIL method distribute the numbers
Answer:
200π
Step-by-step explanation:
Surface area is abbreviated to SA
TOTAL SA of cone = Base area + πrl
Base area = πr² = π x 8² = 64π
Curved SA = πrl = π x 8 x l
to work out l, use pythagoras theorem: √(15)² + (8)² = 17
so, curved SA = π x 8 x 17 = 136π
Total SA of cone = 64π + 136π = 200π
Answer is : 208
Explanation:
200 x (1+4%)
200 x (1+0.04)
200 x 1.04= 208
