So, what you need to do is constantly add by even numbers.

Now, throughout 1 to 3 there is the number 2 between the number from 3 to 7 so it's 4 from 7 to 13 its 6 from 13 to 21.

So, your final answer is going to be 8!

The two spinners below are spun. Find the probability of spinning a 4 and a C.
r-ruslan [8.4K]

Step-by-step explanation:

S = { 1, 2, 3, 4, 5, 6 7, 8 }

n ( S ) = 8

Let A be the event of getting 4,

A = { 4 }

n ( A ) = 1

P ( A )

= n ( A ) / n ( S )

= 1 / 8

Therefore, the probability of spinning a 4 is 1 / 8.

S = { A, B, A, C, A, B }

n ( S ) = 6

Let Y be the event of getting C,

Y = { C }

n ( Y ) = 1

P ( Y )

= n ( Y ) / n ( S )

= 1 / 6

Therefore, the probability of spinning a C is 1 / 6.
