there are 10 cards in A box with number 1 to 10 marked on each of them what is the probability of getting a card with an odd number

the probability is 1/2

Step-by-step explanation:

there are 10 cards.

1,3,5,7, and 9 are all 5 odd numbers.

there are 5 numbers left.

2,4,6,8, and 10 are 5 even numbers.

half the cards are odd and the other half is even.

the probability is 1/2 or a half

i believe the answer is the polygon, heptagon.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
