Answer:
the probability that Jack draws the blue ball is 0.38539
Step-by-step explanation:
Given the data in the question;
box contains
blue balls = 5
red balls = 8
Jim and Jack start drawing balls from the box, respectively, one at a time, at random, and without replacement
Now,
on the first attempted;
⇒ ( 8/13) × ( 5/12) = 10/39
on the second attempt;
⇒ ( 8/13 ) ( 7/12) ( 6/11 ) ( 5/10 ) = 14/143
on the third attempt;
⇒ ( 8/13 ) ( 7/12) ( 6/11 ) ( 5/10 ) ( 4/9 ) ( 5/8 ) = 35/1287
on the fourth attempt;
⇒ ( 8/13 ) ( 7/12) ( 6/11 ) ( 5/10 ) ( 4/9 ) ( 3/8 ) ( 2/7 ) ( 5/6 ) = 5/1287
so we add everything;
⇒ 10/39 + 14/143 + 35/1287 + 5/1287
= 0.38539
Therefore, the probability that Jack draws the blue ball is 0.38539
Answer:
Each side of a square is equal. Thus the distance between 'I' and 'S'=<em> 2cm.</em>
Step-by-step explanation:
First convert all the fractions so that they have a common denominator.
1/2= 8/16
1/8= 2/16 u multiply this by 2 because he is giving 2/16 to each of his 2 children so it’s 4/16
U then multiply 1/16 by 3 because he is giving 1/16 to each of his 3 grandchildren so 3/16 in total
Then add up all these fractions 8/16+4/16+3/16= 15/16
U know that he’s giving away the remaining 15,000 which is 16/16-15/16 so 1/16 of his total estate. Then u can set a proportion to find out his total estate 1/16=15,000/x and u get that x=$240,000
Answer:
The temperature in the Fahrenheit scale is expressed or written in degree Fahrenheit, and the temperature in the Celsius scale is expressed or written in degree Celsius. The relationship between Fahrenheit and Celsius is directly proportional.
