Answer:
26/36
Step-by-step explanation:
The probability of something = the amount of favourable outcomes/total possible outcomes.
The total number of dice combinations is 36 (6x6).
In this case there are more outcomes more than 5 than less than 5 so for the sake of simplicity we are going to find the number of outcomes less than 5 and then find the inverse.
There are only 10 possible dice combos which add to totals 5 or under:
1,1 1,2 2,1 1,3 3,1 1,4 4,1 2,2 2,3 and 3,2
That means there is a 10/36 probability of getting a total score less than 5 so to get the probability of getting more than 5, we just do 36/36 - 10/36 (because all probabilities add to 1)
Therefore there is a 26/36 probability that the toatals will add to greater than 5.
Alternatively you could also draw up a possibilities table and count the favourable outcomes.
Hope this helped!
The denominator of the second fraction can be factored as (a-2)(2a-7), then it becomes doable. You cancel the (2a-7) factors, and are left with:
Do note that you have erased the fact that a≠0 and a≠7/2, so you should always mention that.
Answer:
1/4
Step-by-step explanation:
12/48=.25
.25 in fraction = 1/4
therefore the coupon is for 25% or 1/4 off
Answer: No.
Step-by-step explanation:
Given: A treasure chest sinks at a rate no less than 20 feet per second.
Speed = -20 feet per second.
The depth of ocean = -4200 feet
Since 1 minute = 60 seconds
Therefore 3 minutes=180 seconds
The depth D reached by treasure chest in 3 minutes is given by :-
Clearly -4200<-3600
Therefore, the treasure chest can not reach the ocean floor in less than 3 minutes.
