**There are two names given JOHNSON and TONY. If one letter is picked from both simultaneously at random, then find the probability that the letter is same?**

JOHNSON = 2/7 (if I pick O)

TONY= ¼ (if I pick O)

Total probability of picking O = 2/7 + ¼

JOHNSON = 2/7( if I pick N)

TONY = ¼ ( if I pick N)

Total probability of picking N = 2/7 + ¼

Probability of that the letter is same

= Total probability of picking O * Total probability of picking N

= (2/7 + ¼)*(2/7 + ¼)
