Question

Helen rolls a dice and flips a coin. Calculate the probability that she gets a 4 an d a tail

Answer 1

Step-by-step explanation:

probability of getting 4=1/6

probability of getting a tail = 1/2....

Answer 2

Probability of getting both a FOUR and TAIL simultaneously is 1/12

◆As dice is of six sides, in a single throw,

Probability of getting a FOUR on a dice =1/6,

◆That is , In a dice, there are numbers 1,2,3,4,5,6

For Getting any number , out these six numbers , the probability is 1/6.

◆Flipping an unbiased coin where there is equal probability to get a HEAD and TAIL ,

Probability of getting a TAIL = 1/2

◆For instances occurring SIMULTANEOUSLY, probabilities are MULTIPLIED;

◆9Probability of getting both a FOUR and TAIL simultaneously is = 1/2×1/6=1/12.

◆Hence the solution.
