Question

Answer 1

Answer:

probability of

s= 3

t= 3

i=2

Answer 2

Answer:

4/5

Step-by-step explanation:

probability of getting S , T or I = ( number of times S, T , I occur in the word ) / (total number of letters in the word )

S occurs 3 times

T occurs 3 times

I occurs 2 times

Totally there are 10 letters

so probability of getting S , T or I = ( 3+3+2 ) / ( 10 )

= 8 / 10

= 4/5

so so probability of getting S , T or I = 4/5
