Answer:
P(2, then 2) =
P(3, then 5) =
P(4, then odd) =
Step-by-step explanation:
Given: A fair number cube is rolled
To find: P(2, then 2) , P(3, then 5) , P(4, then odd)
Solution:
Probability refers to chances of occurrence of some event.
Probability = Number of favourable outcomes/Total number of outcomes
Sample space =
Total number of outcomes = 6
P(2, then 2) = P(2)P(2) =
P(3, then 5) = P(3)P(5) =
Odd numbers out of the sample space =
P(4, then odd) = P(4)P(odd) =
Answer:
36 miles
Step-by-step explanation:
His entire journey, represented with a diagram, is in the shape of a right angle triangle.
We need to first find the hypotenuse of the triangle, then, add all the sides together:
hyp² = opp² + adj²
hyp² = 9² + 12²
hyp² = 81 + 144 = 225
Find the square root of both sides:
hyp = 15 miles
Therefore, adding the three sides together:
Total distance traveled = 9 + 12 + 15
Total distance traveled = 36 miles
He would ride 36 miles altogether.
