Question

a mini lottery involves selecting two numbers between 1 and 10. what is the probaility of correctly picking the two numbers?

Answer 1

there are 10 numbers between 1 to 10

the probability of correctly picking the first number is 1/10

the probability of correctly picking a second number is also 1/10

so the overall probability would be 1/10 x 1/10

does that help?

Answer 2

the possibl numbers are 12,23,34,45.56,67,78,89,n other combinations like this are 90 hence the probability may be 9/10
