Answer:
Probability of hitting two times is 0.81, one time is 0.18, zero times 0.01.
Step-by-step explanation:
We need to consider the even as binomial distribution function. Therefore, the probability distribution of the number of hitting times X are:

Step-by-step explanation:
3 sticks of butter make 24 cookies
which means we multiplied 3 by 8
then we devide 16 cookies by 8 which is 2 (as you did)
therefore 5 multiplied by 8 equals 40
Number of pieces of chalk that are yellow is 6
<h3><u>Solution:</u></h3>
Given that there are 18 pieces of chalk
To find: number of pieces of chalk that are yellow
Given that, ratio of chalk that is yellow to chalk that is not yellow is 1 : 2
Therefore,
chalk that is yellow : chalk that is not yellow = 1 : 2
Let the chalk that is yellow be 1x
Let the chalk that is not yellow be 2x
Also, total pieces of chalk = 18
That is,
chalk that is yellow + chalk that is not yellow = 18
1x + 2x = 18
3x = 18
x = 6
number of pieces of chalk that are yellow = 1x = 1(6) = 6
Thus 6 chalk pieces are yellow
