The probability that he hits will a bulls eye with at least one of his next three shots is 98.43%.
<h2><u>
Probabilities</u></h2>
Given that a marksman can hit a bull eyes from 100 m three times out of every four shots, to determine what is the probability that hits will a bulls eye with a least one of his next three shots, the following calculation must be performed:
- Probability of failure: 0.25
- 0.25 x 0.25 x 0.25 = X
- 0.0156 = X
- 1 - 0.0156 = X
- 0.9843 = Chance
Therefore, the probability that he hits will a bulls eye with at least one of his next three shots is 98.43%.

61/90 62/90 63/90 64/90 65/90 66/90 67/90
choose any five :)
Answer:
hope this helps brainliest pls if it is
Step-by-step explanation:
Austin would have 6 jelly beans and Alex would have 18 because if Alex were to have three times as many jellybeans as Austin that means Austin will have one times and Alex would have three times which equals four so you would have to divide 4÷24 which gives them six for each group

Step-by-step explanation:
The data:
![\begin{matrix}i= & 1 & 2 & 3 & 4 & 5 & 6\\X= & 0 & 1 & 2 & 3 & 4 & 5\\P= & 0.6 & 0.2 & 0.12 & 0.4 & 0.4 & 0\end{matrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bmatrix%7Di%3D%20%26%201%20%26%202%20%26%203%20%26%204%20%26%205%20%26%206%5C%5CX%3D%20%26%200%20%26%201%20%26%202%20%26%203%20%26%204%20%26%205%5C%5CP%3D%20%26%200.6%20%26%200.2%20%26%200.12%20%26%200.4%20%26%200.4%20%26%200%5Cend%7Bmatrix%7D)
whereby
correspondingly represent the index number, the number of days absent and the corresponding probability.
Firstly we calculate the expected number of days absent using the following formula:
![E(X)=\sum_{i=1}^{6}X_i P_i = 0.72](https://tex.z-dn.net/?f=E%28X%29%3D%5Csum_%7Bi%3D1%7D%5E%7B6%7DX_i%20P_i%20%3D%200.72)
Subsequently, we calculate the standard deviation using the following formula:
![\\\sigma =\sqrt{\sum_{i=1}^{6}P_i\times[X_i-E(X)]^2}=1.0778](https://tex.z-dn.net/?f=%5C%5C%5Csigma%20%3D%5Csqrt%7B%5Csum_%7Bi%3D1%7D%5E%7B6%7DP_i%5Ctimes%5BX_i-E%28X%29%5D%5E2%7D%3D1.0778)
