A leter is taken out at random from the word 'ASSAM' and a leter is taken out at random from the word 'NAGALAND'. What is the probability that the two leters are the same?
In ASSAM, we have 2As, 2Ss, 1 M In NAGALAND, we have 2Ns, 3As, 1G,1L, 1D 1 letter is taken from each word-That needs to be the same. So, these can be As only. So, probability of A taken from ASSAM is 2C1/5C1 = 2/5 and A from NAGALAND is 3C1/8C1 = 3/8 So, required probability = (2/5)*(3/8) = 3/20
What will come in place of the question mark (?) in the following question?
24.30% of 372.32 = ?
? = 15% of 2400 + 140% of 4200 – 12 3
19 × ? = 361 ÷ 19
‘A’ and ‘B’ invested Rs. 5000 and Rs. 4200, respectively in a business, together. After 7 months, ‘A’ withdrew 25% of his initial investment...
18/2 of 3/9 of 2/6 of 69690 = ?
13/3 – (23/6) = ? – (22/9)
5 × 14 + 100 ÷ 4 = 62 + ?
26 X √25 + 15 - 80% of 120 = ?2
33 × ?2 – 6 × 5 = 3270
16 × 14 + 30 × 21 = 14 × ?
