In order to find the probability of drawing a marble that is NOT BLUE, we must find the ratio of non-blue marbles to the total amount of marbles
Let's count how many marbles total there are first
8 red + 3 blue + 1 green = 12 marbles total
Now, how many marbles are there that <u>ARE NOT BLUE </u>
8 red + 1 green = 9 marbles <u>THAT ARE NOT BLUE </u>
Now<em> let's create a ratio</em> to find a probility
9/12
This can be simplified to 3/4 by taking out the common factor of 3
Your answer is D! "three-fourths"
Answer:
45
Step-by-step explanation:
Answer:
7:24 pm
Time taken will be longer
Step-by-step explanation:
Given that:
Distance between Manchester and London = 195 miles
Departure time = 3.30 pm
Average speed of Coach = 50 mph
Arrival time in London :
Time taken = distance / speed
Time taken = 195 / 50 = 3.9 hours (3 hours (0.9 * 60) = 3 hours 54 minutes
= 3:30 pm + 3 hours 54 minutes = 7:24 pm
If the speed is Lower then the Timetaken will be longer and subsequently coach will arrive after 7:24 pm
