Answer:
The approximate probability that the first letter chosen is A = 0.0385....
Step-by-step explanation:
The given statement is two unique letters are chosen at random from the alphabet.
The total number of ways that the two letters would be chosen from alphabets = 650
26*25 = 650
For the first draw there are 26 letters but for the second draw there are only 25 letters left thats why we have multiplied 26 by 25.
The number of ways letters are chosen such that the first one is A, is
1*25 = 25
Thus the probability that the first letter chosen is A:
P(A)25/650 = 0.03846
By rounding off it becomes 0.0385.
Thus the approximate probability that the first letter chosen is A = 0.0385....
Answer:
It is because he doesn’t know exactly which cards are in the basket and he doesn’t know the exact three he is going to pick out
Step-by-step explanation:
Answer:
a) A sequence is an ordered list of numbers whereas a series is the sum of a list of numbers; b) A series is divergent if it is not convergent. A convergent series is a series for which lim n → ∞ an exists.
Step-by-step explanation:
A sequence is a pattern; it is an ordered list of numbers. A series, however, is the sum of a sequence.
A convergent series is a series for which the sequence of its partial sums tends to a limit; this means the limit exists. A divergent series is a series that is not convergent.
We know that
Law of sines established
a/sin A=b/sin B=c/sin C
then
a/sin A=c/sin C------------> a=c*sin A/sin C---------> a=6*sin 19/sin 102
a=1.91 units <span>≈2 units
A+B+C=180</span>°----------> B=180-(A+C)-----> B=1180-(19+102)
B=59°
a/sin A=b/sin B-----------> b=a*sin B/sin A----->2*sin 59/sin 19
b=5.27 units <span>≈5.3 units</span>
the answer is the option
B = 59°, a ≈ 2, b ≈ 5.3
Answer:
Step-by-step explanation:
Given : The probability that an adult was never in a museum is : p=0.10
The number of adults randomly surveyed: n = 60
In Binomial distribution , the formula to find the mean and the standard deviation is given by :-
Then , the mean and standard deviation of the number that were never in a museum will be :-
