A box contains three cards. On one card there is a question mark (Q), on another card there is a rectangle (R), and on the third card there is a pear (P). Two cards are to be selected at random with replacement. Complete parts (a) through (e) below List the sample space. Choose the correct answer below

QQ QR, QP, RQ, RR, RP. PQ, PR, PP OB.
QR QP, Ra, RP, PQ, PR OC.
QQ, QR, QP, PQ, PR, PP
O D. QR, RP, PQ
c) Determine the probability that two rectangles are selected The probability is(Simplity your answer.)
d) Determine the probability that a card containing a rectangle and then a card containing a question mark are selected The probability is(Simplity your answer.)
e) Determine the probability that at most one card containing a question mark is selected The probability is

(a) QQ, QR, QP, RQ, RR, RP. PQ, PR, PP

(c)

(d)

(e)

Step-By-Step Explanation:

(a)Sample Space

Since there is replacement, for the second pick, we can still pick the previous card.

Therefore, the Sample Space = QQ, QR, QP, RQ, RR, RP. PQ, PR, PP

(c) Probability that two rectangles are selected  

(d) Probability that a card containing a rectangle and then a card containing a question mark are selected.

(e) Probability that at most one card containing a question mark is selected.

huh? im pretty sure it is in 199

step-by-step explanation:

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
