Step-by-step explanation:
The probability of winning at least once is equal to 1 minus the probability of not winning any.
P(x≥1) = 1 - P(x=0)
P(x≥1) = 1 - (1-0.11)^4
P(x≥1) = 1 - (0.89)^4
P(x≥1) = 0.373
The probability is approximately 0.373.

For 7: (7-1)/(1-10) = 6/-9 = -2/3
For 8: (6.1-3.1)/(-5.5 - -2.5) = 3/-3 = -1
For 9: (5/2 - -3) / (-5 - -7/3) = 11/2 / -8/3 = -33/16. This is not an answer option, so double check the problem.</span>
Answer:
2, 6, 12, 20, 30
Step-by-step explanation:
To find the first 5 terms, substitute n = 1, 2, 3, 4, 5 into the rule
a₁ = 1² + 1 = 1 + 1 = 2
a₂ = 2² + 2 = 4 + 2 = 6
a₃ = 3² + 3 = 9 + 3 = 12
a₄ = 4² + 4 = 16 + 4 = 20
a₅ = 5² + 5 = 25 + 5 = 30
Answer:
0.6
Step-by-step explanation:
A permutation is an arrangement of outcomes whereas a combination is a grouping of outcomes.
Order matters in case of permutations but does not matter in combinations.
Given:
Number of red marbles = 3
Number of white marbles = 2
Number of green marbles = 1
To find: probability of picking 4 marbles and getting one of each color
Solution:
Total number of outcomes = =
Number of favourable outcomes = 2 red, 1 white and 1 green marble + 1 red, 2 white and 1 green marble = =
So, probability of picking 4 marbles and getting one of each color = Number of favourable outcomes/Total number of outcomes =
Answer:
B.) Flip a coin for each person on the list. If the coin comes up heads, they will be put in the group that exercises before lunch. If the coin comes up tails, they will be put in the group that exercises after lunch.
D.) The names are put into a bowl and mixed around. The first 50 names drawn will be put in the group that exercises before lunch, and the others will exercise after lunch.
