miskamm [114]

Answer:

3.5x + 2.50y = 1237.50

425 = x + y

Step-by-step explanation:

number of adult tickets: x

number of student tickets: y

3.5x + 2.50y = 1237.50

( value of adult ticket [3.50]* number of adult tickets [x]) + (value of student ticket [2.50] * number of student tickets [y]) = total value (1237.50)

425 = x + y

(number of adult tickets [x]) + (number of student tickets [y]) = total (425)

wolverine [178]

Answer: Option 'A' is correct.

Step-by-step explanation:

In the binomial probability formula, we have

$P(X=x)=^nC_xp^{x}q^{n-x}$

Here, n = number of events

x = number of trials

p = probability of success

q = probability of failure

x is the number of trials among which we decide the number of successes and number of failures.

So, Option 'A' is correct.
