Answer:
1. 3/8
Step-by-step explanation:
Total tossed times = 3
Total Possibilities = 8
Possibilities = (Head, Head, Head), (Tails,Tail,Tails), (Head,Head,Tails), (Head,Tail,Head), (Tails,Head,Head), (Head,Tail,Tail), (Tail,Tail,Head), (Tail,Head,Tail)
Number of options with a head and two tails = 3
So, Probability = Number of correct options ÷ Number of total possibilities
= 3 ÷ 8 or 3/8
