26) In a class of 30 students, approximately what is the probability that two of the students have their birthday on the same da
Art [367]

Answer:

Answer is 0.696

Step-by-step explanation:

The sum number of sets possible for no two students to have the same birthday in a class of 30 is:

=30 * (30-1)/2

= 435.

Now, there are 365 days in a year. Therefore, the probability of students having a  birthday on a different date would be 364/365. Now there are a number of combination, to be exact 870 combinations.

So, the probability that no two students having the same birthday is:

(364/365)^435 = 0.303.

Now, the probability that two students would have their birthdays on the same equal date would be:

1-0.303 = 0.696 or 70%

Let Upper A equals left bracket Start 2 By 2 Matrix 1st Row 1st Column negative 2 2nd Column 4 2nd Row 1st Column 1 2nd Column 3
Yuliya22 [10]

Answer: a) AB = \left[\begin{array}{ccc}-14&26\\-11&22\end{array}\right] ; b) \left[\begin{array}{ccc}5&-5\\13&9\end{array}\right] ; c) No, they are different; d) No, they are never the same;

Step-by-step explanation:

a) A = \left[\begin{array}{ccc}-2&4\\1&3\end{array}\right] , B = \left[\begin{array}{ccc}-2&1\\-3&7\end{array}\right]. This multiplication is possible, because matrix A has 2 columns and matrix B has 2 rows. When those value are equal, the multiplication is possible.

AB = \left[\begin{array}{ccc}-2&4\\1&3\end{array}\right] . \left[\begin{array}{ccc}-2&1\\-3&7\end{array}\right] = \left[\begin{array}{ccc}-14&26\\-11&22\end{array}\right]

b) BA = \left[\begin{array}{ccc}-2&1\\-3&7\end{array}\right] . \left[\begin{array}{ccc}-2&4\\1&3\end{array}\right] = \left[\begin{array}{ccc}5&-5\\13&9\end{array}\right]

c) As, we can see, parts a and b are differents.

d) With matrices, multiplication is not commutative, which means AB≠BA
