A jockey will ride horses in 10 different races at a race track today. The number of races that the jockey will win is what type of random variable

X is a discrete Random variable where X is the number of races Jockey can win.

Step-by-step explanation:

To find - A jockey will ride horses in 10 different races at a race track today.

The number of races that the jockey will win is what type of random variable ?

Proof -

Given that,

A jockey will ride horses in 10 different races at a race track today.

Let us assume that,

X is the number of races Jockey can win

So,

X can take value 0, 1, 2, 3, 10

As,

It can take countable finite values

So,

X is a discrete Random variable

∴ we get

X is a discrete Random variable where X is the number of races Jockey can win.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

what is the question?
