Answer:
the probability of picking an odd number is 7/10
The probability of getting an odd number is 7/10.
Step-by-step explanation:
There are 7 odd numbers: {1, 3, 7, 9, 15, 19, 21}
There are 3 even numbers: {2, 10, 20}
There are 10 numbers overall: {1, 2, 3, 7, 9, 10, 15, 19, 20, 21}
7 odd numbers out of 10 numbers is equal to 7/10
D
well, we just need to substitute the known point to each option.
5 to 6 or 30 to 36
15/3=5, 18/3=6, 15*2=30,18*2=36
C
I believe it is C. If the temperature dropped, it means it went down, so a negative option makes sense. To check, use the process of elimination.
A: The temperature dropped, not rose.
B: It only dropped 15 degrees, not 151.
D: It dropped, not rose, and only dropped 15 degrees.
