Question

Teacher asked a student to say a two digit number, a)What is the probability of that number being 17? b)What is the probability of it being a perfect square​

Answer 1

Answer:

a)0.01123595505 or simply 0.011

b)0.06741573033 or simply 0.067

Step-by-step explanation:

Here, let's take the total number of outcomes as "n"

a)P[A]= No. of outcomes favourable to E/Total No. of outcomes

where A stands for "Event"

P[A] = 1/n

= 1/89

= 0.011

b) There are total 6 perfect two digit squares they are 16,25,36,49,64, and 81

hence

P[B] = 6/n

where B stands for Event

= 6/89

= 0.067
