John and Jane are married. The probability that John watches a certain television show is .5. The probability that Jane watches

Tanzania [10]

Answer: a) 0.15

b) 0.300

Step-by-step explanation:

Given : The probability that John watches a certain television show : P(John)=0.5

The probability that Jane watches the show is : P(Jane)= 0.5.

The probability that John watches the show, given that Jane does

=P(John | Jane)=0 .3.

Using Condition probability formula $P(B|A)=\dfrac{P(A\cap B)}{P(A)}$ , we have

$P(A\cap B)=P(B|A)\timesP(A)$

Similarly,

a) The probability that both John and Jane watch the show will be :-

$\text{P(John}\cap \text{Jane)}=\text{P(John }|\text{ Jane)}\times\text{P(Jane)}\\\\=0.3\times0.5=0.15$

b) The probability that Jane watches the show, given that John does will be :-

$\text{P(John }|\text{ Jane)}=\dfrac{\text{P(John}\cap \text{Jane)}}{\text{P(John)}}\\\\=\dfrac{0.15}{0.5}=0.3$

Hence, the probability that Jane watches the show, given that John does. = 0.300

irakobra [83]

Answer:

(a)6.82mph

(b)22 ft/sec

Step-by-step explanation:

Eric's Speed = 10 ft/sec

The Ferry's Speed = 15 miles per hour

Conversion Unit

1 mile = 5280 feet
1 hour = 3600 seconds

Guide

When converting from a smaller unit to a larger unit we divide
When converting from a larger unit to a smaller unit we multiply

(a)To convert Eric's Speed 10 ft/sec to miles per hour

$\dfrac{10 \:ft}{seconds} =\dfrac{10 \div 5280 \:miles}{1 \div 3600\: hour} \\=6.82 miles \:per\: hour$

(b)To convert the Ferry's Speed 15 mph to ft/sec

$\dfrac{15 \:miles}{hour} =\dfrac{15 X 5280 \:foot}{1 X 3600\:seconds} \\=22 foot \:per\: seconds$
