Answer:
Okay, So neither a spade nor a jack.
Total no. of cards in adeck =52
Number of spades =13
Total number of non-spades out of 52 cards =52−13=39
Number of jack out of 52 cards =4
Number of jack in each of three suits namely hearts, diamonds and clubs = 3
[Since, 1 jack is already included in the 13 spades so, here we will take number of jacks is 3 ]
Neither a spade nor a jack =39−3=36 cards in total.
Therefore, probability of getting ‘neither a spade nor a jack’=

Answer:
(a) 1024 ways
(b) 243 ways
Step-by-step explanation:
When answers are independent, the total number of ways all questions can be answered is the product of the number of ways each question can be answered.
__
<h3>(a)</h3>
The first question can have one answer 4 ways. The second question can be answered 4 ways for each of the ways the first question was answered. That is, the two questions can be answered 4×4 = 16 ways. Similarly, each additional question multiplies the number of ways the questions can be answered by 4.
The 5 questions can be answered 4×4×4×4×4 = 4^5 = 1024 ways.
__
<h3>(b)</h3>
There are 3 ways to answer the first question incorrectly. Each additional question can be answered incorrectly 3 ways for each of the ways previous questions were answered. The total number of ways all questions can be answered incorrectly is ...
3^5 = 243
A student can answer all questions wrong in 243 different ways.
y = -|x + 4|
The coordinates of vertex of that function is (x; 0).
-|x + 4| = 0
|x + 4| = 0 ⇔ x + 4 = 0 |-4
x = -4
Answer: (-4; 0)
Answer:
2.35 x 24 = 56.4
