0.25q + 0.10d = 2.95
q = d + 9

0.25(d + 9) + 0.10d = 2.95
0.25d + 2.25 + 0.10d = 2.95
0.25d + 0.10d = 2.95 - 2.25
0.35d = 0.70
d = 0.70/0.35
d = 2 <=== 2 dimes

q = d + 9
q = 2 + 9
q = 11 <=== 11 quarters

bagirrra123 [75]

Answer: $\dfrac{2}{9}$

Step-by-step explanation:

Given

The spinner has 6 equal sections A, B, C, D, E, and F

The two events occurred one after the other. So, the probability is the product of the probabilities of each event.

There are two consonants in the given 6 letter

The probability of landing over a consonant is

$P_1=\dfrac{2}{6}$

The number greater than 2 in a cube are 3,4,5,6

So, probability corresponding to it

$P_2=\dfrac{4}{6}$

So, the required probability is

$\Rightarrow P=P_1\times P_2\\\Rightarrow P=\dfrac{2}{6}\times \dfrac{4}{6}\\\\\Rightarrow P=\dfrac{8}{36}\\\\\Rightarrow P=\dfrac{2}{9}$
