John rolls a six-sided number cube twice. What is the probability of getting an even number and then an odd number?
2 answers:
Answer:
Step-by-step explanation:
Given : John rolls a six-sided number cube twice.
Total number of outcomes on a fair cube = 6
When we roll two dices , then the total number of outcomes :-
Number of favorable outcomes of getting an even number and then an odd number :-
[since there are 3 odd and 3 even numbers on it]
Now, the probability of getting an even number and then an odd number =

The horse traveled 439.6 feet after walking around the track 5 times
<u><em>Solution:</em></u>
Given that, horse walks around a circular track while its trainer stands in the center
The trainer is 14 feet from the horse at all times
Therefore, radius of circular track = 14 feet
The circumference of circle is the distance traveled by horse for 1 lap
<em><u>The circumference of circle is given as:</u></em>
Where, "r" is the radius and is a constant equal to 3.14
Thus the distance traveled by horse for one time in circular track is 87.92 feet
<em><u>About how far had the horse traveled after walking around the track 5 times? </u></em>
Multiply the circumference by 5
Thus the horse traveled 439.6 feet after walking around the track 5 times
Answer: B) 67%
<u>Step-by-step explanation:</u>
Find the Area of the Bullseye and Middle ring
A = π r²
A (inside) = π(8)² = 64π
Find the Area of the entire Target
A (target) = π (14)² = 196π
Find the Area of the Outer ring
A (outer ring) = A (target) - A(inside)
= 196 π - 64π
= 132 π
The last step is to find the probability of landing on the outer ring:
