Answer:
1). 0.903547
2). 0.275617
Step-by-step explanation:
It is given :
K people in a party with the following :
i). k = 5 with the probability of ![$\frac{1}{4}$](https://tex.z-dn.net/?f=%24%5Cfrac%7B1%7D%7B4%7D%24)
ii). k = 10 with the probability of ![$\frac{1}{4}$](https://tex.z-dn.net/?f=%24%5Cfrac%7B1%7D%7B4%7D%24)
iii). k = 10 with the probability ![$\frac{1}{2}$](https://tex.z-dn.net/?f=%24%5Cfrac%7B1%7D%7B2%7D%24)
So the probability of at least two person out of the 'n' born people in same month is = 1 - P (none of the n born in the same month)
= 1 - P (choosing the n different months out of 365 days) = ![1-\frac{_{n}^{12}\textrm{P}}{12^2}](https://tex.z-dn.net/?f=1-%5Cfrac%7B_%7Bn%7D%5E%7B12%7D%5Ctextrm%7BP%7D%7D%7B12%5E2%7D)
1). Hence P(at least 2 born in the same month)=P(k=5 and at least 2 born in the same month)+P(k=10 and at least 2 born in the same month)+P(k=15 and at least 2 born in the same month)
= ![\frac{1}{4}\times (1-\frac{_{5}^{12}\textrm{P}}{12^5})+\frac{1}{4}\times (1-\frac{_{10}^{12}\textrm{P}}{12^{10}})+\frac{1}{2}\times (1-\frac{_{15}^{12}\textrm{P}}{12^{15}})](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%5Ctimes%20%281-%5Cfrac%7B_%7B5%7D%5E%7B12%7D%5Ctextrm%7BP%7D%7D%7B12%5E5%7D%29%2B%5Cfrac%7B1%7D%7B4%7D%5Ctimes%20%281-%5Cfrac%7B_%7B10%7D%5E%7B12%7D%5Ctextrm%7BP%7D%7D%7B12%5E%7B10%7D%7D%29%2B%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%281-%5Cfrac%7B_%7B15%7D%5E%7B12%7D%5Ctextrm%7BP%7D%7D%7B12%5E%7B15%7D%7D%29)
= ![0.25 \times 0.618056 + 0.25 \times 0.996132 + 0.5 \times 1](https://tex.z-dn.net/?f=0.25%20%5Ctimes%200.618056%20%2B%200.25%20%5Ctimes%200.996132%20%2B%200.5%20%5Ctimes%201)
= 0.903547
2).P( k = 10|at least 2 share their birthday in same month)
=P(k=10 and at least 2 born in the same month)/P(at least 2 share their birthday in same month)
= ![$0.25 \times \frac{0.996132}{0.903547}$](https://tex.z-dn.net/?f=%240.25%20%5Ctimes%20%5Cfrac%7B0.996132%7D%7B0.903547%7D%24)
= 0.0.275617
