Answer:
1.701
Step-by-step explanation:
the word OF means to multiply
so in order to do this..
FIRST: make 10% into .10 because the % sign goes 2 times to the right
SECOND: you do .10 times 17.01
FINALLY: you get 1.701
Probability of winning a grand prize is 1/10
Probability of winning a basic prize is 11/20
What is the probability of two independent events?
If A and B are two independent events, then P(A and B) = P(A) * P(B).
If Events A and B are independent, the probability that either Event A or Event B occurs is: P(A or B) = P(A) + P(B) - P(A and B).
Solution:
P(A) = no. of A / total possibility
= 4/10
P(B) = no. of 1's/total possibility
= 3/12
= 1/4
Now,
To win a grand prize you need an "A" and "1" .
∴ P(A and B) = P(A) × P(B)
= 4/10 × 1/4
P(A and B) = 1/10
Now ,
To win a basic prize you need to spin an "A" or a "1"
∴ P(A or B) = P(A) + P(B) - P(A and B)
= 4/10 + 1/4 - 1/10
= 3/10 + 1/4
∴ P(A or B)= 11/20

Responder:
Tn = 4n + 1
Explicación paso a paso:
Dada la secuencia aritmética
5,9,13,17,21 ...
Debemos encontrar el enésimo término de la secuencia
Tn = una + (n-1) d
a es el primer término = 5
n es el número de términos
d es la diferencia común
d = 9-5 = 13-9
d = 4
Sustituir en la ecuación
Tn = 5+ (n-1) (4)
Tn = 5 + 4n-4
Tn = 4n + 5-4
Tn = 4n + 1
Por tanto, el enésimo término de la secuencia se expresa como Tn = 4n + 1
