Question

two digit numbers are formed by the digits 0,1,2,3,4 wher the digits are not repeated.find the probability that 1 .the number formed is grater than42 .2.the number formed is a multiple of 4​

Answer 1

Answer:

1/16 and 5/16

Step-by-step explanation:

we can form 16 two digit numbers=10, 12, 13, 14, 20, 21, 23, 24 30, 31, 32, 34, 40, 41, 42, 43

only 43 is greater than 42 so

n(S)=16

let p be the case where number is greater than 42

n(p)=1

P(p)=1/16=1/16

2)sample space=10, 12, 13, 14, 20, 21, 23, 24 30, 31, 32, 34, 40, 41, 42, 43

favourable outcomes-12,20,24,32,40,

probability=5/16
