Alenkinab [10]

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%)

Tasya [4]

The racer take 4 hours (between 8:00 to 12:00) to race 3/4 of 6 miles

3/4 of 6 miles = 18/4 = 4.5 miles

4 hours ⇒ 4.5 miles
1 hour ⇒ 4.5 ÷ 4 = 1.125 miles

The time taken to complete 6 miles = 6 ÷ 1.125 = 16/3 hours = 5.3 hours

Answer:

0.8

Step-by-step explanation:

Given that, the green skin (G) is dominant to yellow (Y). Cross between the green creature and yellow creature will have the offspring with the following genotypes.

Gg* yy = Gy, Gy, gy, gy (Means, 1:1 ratio of green and yellow offspring, but the observed values are in 3:2 (12:8) ratio).

Now, the Chi-square value can be calculated as follows. (O= Observed, E= Expected)
