Answer:
See below.
Step-by-step explanation:
See the attached chart that shows all outcomes for two dice.
There are 36 possible outcomes, all equally likely (if the dice are fair!).
The probability of getting a sum of 2 is 1/36 (only one way to get 2: both dice show 1).
The probability of getting a sum of 3 is 2/36 = 1/18.
The probability of getting a sum of 7 is 6/36 = 1/6 (the most likely sum!)
(Notice how all the sum = 7 outcomes like on a diagonal in the chart?)
The probability of getting a sum of 11 is 2/36 = 1/18.
The probability of getting a sum of 12 is 1/36.

Answer:
21.63 m
Step-by-step explanation:
Given :
Hypotenus = 42 m
Base = 36 m
Hence, using Pythagoras rule :
Opposite = √hypotenus² - Adjacent²
Height = √42²-36²
Height = √1764 - 1296
Height = √468
= 21.63 m
Answer with explanation:
The 90% confidence interval (51%, 61%) for proportion means that the proportion of getting heads lie in it.
Given : Total number of times coin is tossed = 250
Number of times they got head =140
The probability of getting a head = 0.56
The confidence interval for proportion is given by :-
Given significance level :
Critical value :
Now, the 90% confidence interval for proportion will be :-
Hence, the given confidence interval is correct.
