48 can be written as the product of two different numbers a and b such as 48 = a*b. What is the prob

Supriya Mondal   9 years AGO

48=a*b
We, can write a and b in the following manner
48=1*48
48=2*24
48=3*16
48=4*12
48=6*8
48=8*6
48=12*4
48=16*3
48=24*2
48=48*1
So, probability that a is 3 will be=1/10
So, option 6)1/10 is the right answer

Possibilities
1*48, 2*24, 3*16, 4*12, 6*8

a*b could be:
8*6, 6*8
4*12, 12*4
16*3, 3*16
24*2, 2*24
48*1, 1*48

one possibility for 3 i.e is 3*16

total number of possibilities that a*b = 48 is 10

hence 1/10

answer is option 6

Shiva Teja   9 years AGO

There are 10 ways 48 can be written as product of two different numbers i.e, as a*b
1*48
2*24
3*16
4*12
6*8
8*6
12*4
16*3
24*2
48*1

Out of these 10 possibilities 3 comes in first position of (a*b) (that is at a) in only one case i.e, 3*16

Therefore probability is 1/10

There are10 such combinations posible as shown:
48=1*48
48=2*24
48=3*16
48=4*12
48=6*8
48=48*1
48=24*2
48=16*3
48=12*4
48=8*6
But favourable is one 3*16

Rahul R Bharadwaj   9 years AGO

find all the divisors of 48: 1,2,3,4,6,8,12,16,24,48
all possible pairs are made by choosing first and last digit( as product must be 48) . Now the number of pairs is 5, but (1,48) and (48,1) both are possible, so Total Pairs:10;
Now a=3, only for b=16, so its one pair among 10, hence probability is (1/10)

Like? Yes (1) | No   

SHAIK AYESHA   9 years AGO

48 is divisible by 10 numbers i.e 1,2,3,4,6,8,12,16,24,48
