Answer:
Whitley owns 2 of the cards
Step-by-step explanation:
In math "of" means to multiply. So Whitley owns 1/4 the collection meaning we multiply 1/4 by 8 to find how how many he owns. When multiplying fractions multiply the numerators together and the denominators together. We can give 8 a denominator of 1 since anything divided by 1 is just itself. So
1/4 times 8/1=8/4=2

Step-by-step explanation:
Answer: the two trains will meet in 2.8 hours
Step-by-step explanation:
Step 1
Speed of train A = 90mph
Speed of train B = 110 mph
Since both trains are travelling towards each other
, their effective speed will be= 90 mph + 110mph= 200mph
Step 2
we know that Speed = distance / time
therefore Time = Distance / speed
Distance = 560 miles
Speed = 200 mph
Time = 560miles / 200mph
2.8 hours
Answer:

And we can find the individual probability like this:

And replacing we got:

Step-by-step explanation:
Assuming the following question: With the salary cap in the NFL, it is said that on any given Sunday any team could beat any other team. If we assume every week of the 16 week season a team has a 50% chance of winning, what is the probability that a team will have at least 1 win?
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want this probability:

And using the complement rule we got:

And we can find the individual probability like this:

And replacing we got:
