First, let's count:
there are 26 possible outcomes for E1 (black card)
there are 4x9 = 36 possible outcomes for E2, to pick a numbered card (any color)
there are 2x9 =18 possible outcomes for E1 (black) AND E2 (numbered, spade + clower)
the probability of E1 AND E2 is the ratio of the count of possible outcomes for E1 + E2 and the count of all possible outcomes (52 choices to pick a card from the deck):
P(E1 and E2) = 18/52 (34.6%)
And as asked:
P(E1) = 26/52 = 1/2 (50%)
P(E2) = 36/52 = 9/13 (69.2%)
Answer: X = 13
Step-by-step explanation:
10 + 3 = 13
13 - 10 = 3
Answer:
volume of box = l*b*h
= 8/9*5/12*3/10
= 1/9 cubic feet
Step-by-step explanation:
This formula is used to find the median in a group data which is located in the median class. Median, m = L + [ (N/2 – F) / f ]C
L means lower boundary of the median class N means sum of frequencies F means cumulative frequency before the median class.
Hope this helps :))
Answer:
$18.40
Step-by-step explanation:
480/30= 16
$16 is the amount earned per hour
16×.15= 2.40
$2.40 is 15% increase in the amount she earns per hour
16+2.40=18.40
$18.40 is hourly rate in dollars after the increase
