Suppose you toss a coin 100 times and get 71 heads and 29 tails. Based on these results, what is the probability that the next flip results in a head?

0.71

Step-by-step explanation:

When a coin is tossed 100 times, it yields heads 71 times and tails 29 times.

So the probability of heads = Number of heads/Total number of tosses

=

=

Similarly, probability of tails = Number of tails/Total number of tosses

=

=

So the probability that the next flip results in a head = Probability of heads in the toss = 0.71

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
