Step-by-step explanation:
given data:
no of cards left = 15.
no of diamonds left = 5.
probability of drawing a diamond = 5/15.
probability that the next two cards drawn to anika are diamonds without replacements.
= 5/15 * 4/14
= 2/21
= 0.0952 * 100
the probability that the two cards dealt to Anika would be diamond is 9.52% ~ 10%

A proportion looks like this:
It means that the quantity a,b,c and d are in the same proportion: the ratio between a and b is the same ratio between c and d.
They are particularly useful in situation when you have an example given, and you want to extrapolate the relationship for another couple.
For example, you can think of the following problem: "Five apples cost 2 dollars. How much will 8 apples cost?"
You can build the proportion
And then solve it for x:
