Given that, in a certain school, the following are true, what is the probability that a student is taking math or computer scien
Serhud [2]

Answer:

The probability that a student is taking math or computer science is 0.37

Step-by-step explanation:

The probability that a student is taking math =P(M)=33% =0.33

The probability that a student is taking computer science =P(C)= 62%=0.62

The probability that a student is taking math and computer science =P(M∩C)= 58%=0.58

So, the probability that a student is taking math or computer science i.e.P(M∪C)

So, Formula:P(A∪B)=P(A)+P(B)-P(A∩B)

P(M∪C)=P(M)+P(C)-P(M∩C)

P(M∪C)=0.33+0.62-0.58

P(M∪C)=0.37

Hence the probability that a student is taking math or computer science is 0.37

Which spreadsheet would be used to compute the first five partial sums o the arthmetic series? an=-5(n-1)+8
Kruka [31]

The nth term of the arithmetic series is given by

a_n=-5(n-1)+8

Now find the first five terms a_1, a_2, a_3, a_4, a_5:

a_1=-5(1-1)+8=8

a_2=-5(2-1)+8=3

a_3=-5(3-1)+8=-2

a_4=-5(4-1)+8=-7

a_5=-5(5-1)+8=-12

Thus the first five terms of the series is 8,3,-2,-7,-12.

Now find the partial sum of the series:

S_1=a_1=8

S_2=a_1+a_2=8+3=11

S_3=a_1+a_2+a_3=8+3-2=9

S_4=a_1+a_2+a_3+a_4=8+3-2-7=2

S_5=a_1+a_2+a_3+a_4+a_5=8+3-2-7-12=-10\\
