Answer:
D. 15×4/100×4 = 60/400
Step-by-step explanation:
First I figured out how many photos there are in total, which was by doing 60/.15, since only 15% of the total photos are in black and white. We can already cross out all possibilities that don't have the denominator 400, but we can go a step further by seeing which one is 60/400, or equal to 60/400, which is D. 15×4/100×4 = 60/400.
Answer:
The ODDS that the dart hits a date that is a prime number are 1:1
Step-by-step explanation:
Odds:
An odd is writen as:
Number of desired outcomes: Number of undesired outcomes.
In this question:
April has 30 days, 15 of which are prime numbers and 15 of which are odd numbers.
So the odds are:
15:15
Simplifying by 15
1:1
The ODDS that the dart hits a date that is a prime number are 1:1
