Here are 10 test scores: 30, 74, 76, 77, 78, 79, 80, 80, 82, 84. The mean of these scores is 74.

creativ13 [48]

We add up all those numbers (excluding 30) and divide by the number of numbers (9). This results in 78.8 (round up to 79).

79-74 = 5. So the mean has increased by 5 points. (C)

Cards are drawn from a standard 52-card deck until the third club is drawn. After each card is drawn, it is put back in the deck

OLEGan [10]

Answer:

Step-by-step explanation:

Given that cards are drawn from a standard 52-card deck until the third club is drawn.

With replacement:

Drawing 3 club prob = 1/52 and non club = 51/52

a) Hence Prob (3rd club is drawn on the 8th selection)

= P(7 non 3 clubs, and one 3 club)

= $(\frac{51}{52} )^7 (\frac{1}{52})$

b) P(first 7 cards non 3 club) = $(\frac{51}{52} )^7$

With replacement

c) P(7 non 3 clubs and 8th 3club)

= $\frac{51C7 }{52C8}$

d) P(atleast first 7 cards non3 club) =1-P(3 club in the 7th draws )= $1-\frac{51C7 }{52(52C8)}$
