(urgent) the probability distribution of a 3-coin toss is shown in the table.

what is the probability that the number of heads will be odd?

a 1/4

b 1/8

c 1/2

d 3/8

We're looking for the probabilities of getting 1 head or 3 heads, which have the probability values of 3/8 and 1/8 respectively

Add those probabilities: 3/8 + 1/8 = (3+1)/8 = 4/8 = 1/2

C 1/2

Step-by-step explanation:

P (heads is odd)

P (heads is 1 or 3)   When it is an or, we add the probabilities

P (heads is 1) + P (heads is 3)

3/8 + 1/8

4/8

1/2

three-fourths of an hour

36÷48=0.75

0.75=

$320 to $405

step by step explanation:

in one day he earns between $64 and $81

therefore if he works for 5 days, he will earn between 64 x 5 to 81 x 5

= $320 to $405
