Answer:
For 0 correct answer ![^4c_0p^0q^{4-0}](https://tex.z-dn.net/?f=%5E4c_0p%5E0q%5E%7B4-0%7D)
For 1 correct answer ![^4c_1p^1q^{4-1}](https://tex.z-dn.net/?f=%5E4c_1p%5E1q%5E%7B4-1%7D)
For 2 correct answer ![^4c_2p^0q^{4-2}](https://tex.z-dn.net/?f=%5E4c_2p%5E0q%5E%7B4-2%7D)
For 3 correct answer ![^4c_3p^1q^{4-3}](https://tex.z-dn.net/?f=%5E4c_3p%5E1q%5E%7B4-3%7D)
For 4 correct answer ![^4c_4p^1q^{4-4}](https://tex.z-dn.net/?f=%5E4c_4p%5E1q%5E%7B4-4%7D)
Step-by-step explanation:
It is given that there are 4 questions n = 4
Number of choices is 4
So probability of getting correct answer ![=\frac{1}{4}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B4%7D)
Probability of getting incorrect answer ![=1-\frac{1}{4}=\frac{3}{4}](https://tex.z-dn.net/?f=%3D1-%5Cfrac%7B1%7D%7B4%7D%3D%5Cfrac%7B3%7D%7B4%7D)
Probability distribution is given by ![^nc_rp^rq^{n-r}](https://tex.z-dn.net/?f=%5Enc_rp%5Erq%5E%7Bn-r%7D)
Therefore probability distribution of 0 correct answer
![^4c_0p^0q^{4-0}](https://tex.z-dn.net/?f=%5E4c_0p%5E0q%5E%7B4-0%7D)
Therefore probability distribution of 1 correct answer
![^4c_1p^1q^{4-1}](https://tex.z-dn.net/?f=%5E4c_1p%5E1q%5E%7B4-1%7D)
Therefore probability distribution of 2 correct answer
![^4c_2p^0q^{4-2}](https://tex.z-dn.net/?f=%5E4c_2p%5E0q%5E%7B4-2%7D)
Therefore probability distribution of 3 correct answer.
![^4c_3p^1q^{4-3}](https://tex.z-dn.net/?f=%5E4c_3p%5E1q%5E%7B4-3%7D)
Therefore probability distribution of 4 correct answer.
![^4c_4p^1q^{4-4}](https://tex.z-dn.net/?f=%5E4c_4p%5E1q%5E%7B4-4%7D)
Answer:
