Answer:

Expectation of the contest = $0.08

Step-by-step explanation:

Amount of the contest prize = $80000

Total entries received = 1 million

Probability of winning the contest = \frac{1}{1000000}

Expectation of the contest will be determined by the formula

P = (winning amount) × (probability to win the contest)

  = 80000\times \frac{1}{1000000}

  = $0.08

Therefore, the expectation of the contest will be $0.08.

aliya0001 [1]

Answer: The observed ratio is different from the expected ratio.

Step-by-step explanation:

Expected ratio :

Ratio of blue flowered plants to white flowered plant = 3:1

Observed results:

Number of blue flowered plants = 35

Number of white flowered plants = 14

So, Ratio of blue flowered plants : white flowered plants

35:14\\\\=5:2

So, 5:2 ≠ 3:1

Hence, the observed ratio is different from the expected ratio.
