Answer 1

Step-by-step explanation:

P(e) = 200/1000

= 1/5

#666

Answer 2

As you can see,

Let E be the outcome of getting at least two tails.

E={TT}

n(E)=250 (Zero Heads means both tails)

n(S)=1000(total no. of outcomes)

P(E)=n(E)/n(S)

=>250/1000

P(E)=1/4

Hence, the correct answer is 2) 1/4
