Well:
100/7= 1/7 probability
1/7 probability (in percent) x 5= 5/7 probability
5/7 probability= 71.4%
33+11+55/3
so 33+11=44
44+55=99 now divide 99 by 3 to get 33
Probablity is (desired outcomes)/(total possible)
desired is your tickets: 5
total possible=500
probability is 5/500=1/100=1%
A ratio can be written 3 ways.
1. a to b
2. a:b
3. a
----
b
Now when we are working with ratios we ALWAYS put the numbers the way the question asks.
It says wat is the ratio of cheese pizzas to pepperoni pizzas sold each week, So we need to put the amount of cheese pizzas 1st, then the amount of pepperoni pizzas.
45:20
45 to 20
45
------
20
Now we will SIMPLIFY.
45 ÷ 5 = 9
20 ÷ 5 = 4
So, our new ratio would be C. 9:4.
Hope I helped ya!!
