dolphi86 [110]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

y = ( {x}^{2}  + 2x + 1) - 1

y =  ({x + 1})^{2} - 1

y =  ({x + 1})^{2} -  ({1})^{2}

We're done now but I have something to tell...

##############################

Hint :

{a}^{2} -  {b}^{2}  = (a + b)(a - b)

##############################

y = ( \: (x + 1)  + 1)( \: (x + 1) - 1) \\

y = (x + 2)(x)

Of students in the AP curriculum at a prep school, 40% take one AP exam, 45% take two AP exams, and the remaining 15% take 3 AP
aliya0001 [1]

It should be noted that the probability that a student will earn at least one 5 will be 0.3152.

<h3>How to calculate the probability</h3>

Test P(x). P(at least one 5)

1. 0.4. 0.2

2. 0.45. 0.36

3. 0.15. 0.488

Therefore, the probability that a student in the AP curriculum will earn at least one 5 will be:

= (0.4 × 0.2) + (0.45 × 0.36) + (0.15 × 0.488)

= 0.3152

In conclusion, the correct option is 0.3152.
