Question

an unbased coin tossed thrice. find the probability of getting head all the three times.​

Answer 1

Answer:

total number of possible outcome=8

number of favourable outcome=1

therefore probability of getting all three head =1/8

Answer 2

Step-by-step explanation:

Total no.of outcomes = 8

Sample space= { HHH,HHT,HTT,HTH,TTT,TTH,THT,THH}

No. of favourable outcomes (i.e. head all three times)= { HHH}

Therefore, P(E)= No. of favourable outcomes/Total no. of outcomes

= 1/8
