Answer:
The approximate probability of winning 4 games in a row is 0.012
Step-by-step explanation:
From the question, the probability of winning the shell games if you randomly pick is 1 in 3, that is,
P(Win) = 1/3
Now, the probability of winning 4 games in a row will be
P (winning 4 games in a row) = P(winning 1st game) × P(winning 2nd game) × P(winning 3rd game) × P(winning 4th game)
P (winning 4 games in a row) = (1/3) × (1/3) × (1/3) × (1/3)
P (winning 4 games in a row) = 1/81 or 0.012
Hence, the approximate probability of winning 4 games in a row is 0.012
Haley’s Percentage Decrease from Test 1 to Test 2 to the nearest tenth is 7.5%
Nearest tenth can be defined as , Look at the hundredth number to round the decimal number to the nearest tenth. If it's more than 5, add one to the tenth value. Remove all the numbers that are present after the tenth place and leave the tenth place value alone if it is less than 5
Given that,
Haley’s Percent score in Test 1 = 93 %
Haley’s Percent score in Test 2 = 86%
Formula For calculating the Percentage Decrease is :
(Beginning Percentage – Final Percentage) / Beginning Percentage * 100
So, by using this formula we can calculate the percentage decrease of Haley’s Test
Percentage Decrease = (93% - 86%)/93% * 100
= 7.5%
