Answer:
11/21
Step-by-step explanation:
34 and the 10 numbers in the 40s have at least one 4. If you include 30 and 50 in the range you're choosing from, then 11 out of the 21 numbers have at least one 4.
A randomly chosen integer from [30, 50] has a probability of 11/21 of having at least one 4.
2 white pens: 8 green pens
add these together to get how many total pens you are talking about
2 white pens + 8 green pens = 10 pens total.
However there are a total of 30 pens.
30 ÷ 10 = 3
that means that there are 3 sets of 10 pens.
2 white pens: 8 green pens
we can multiply the original ratio all by 3
3 x (2 white pens: 8 green pens)
6 white pens: 24 green pens
add these together to get how many pens you are talking about
6 + 24 = 30 total pens.
this means out of 30 total pens, 6 of them are white
