**Hint:**

Probability of event is equal to $\dfrac{{{\text{Favourable outcomes }}}}{{{\text{Total number of outcomes }}}}$ In the part (i) Total number of red cards in a deck of card is $13 + 13 = 26$ ,Total queens are $4$ in which $2$ are red and $2$ are black.

In the part (ii) Total number of Spade cards in a deck of cards is $13$ Total Jacks are $4$ in which $1$ are spade and $3$ are non- spade.

**Complete step by step solution:**

In this question we have to find the probability of a well shuffled pack of $52$ cards ,

In the part (i)

It is given that the Is either a queen or a red card So ,

Total number of cards in a pack $52$

Total number of red cards in a deck of card is $13 + 13 = 26$

Total queens are $4$ in which $2$ are red and $2$ are black.

Total number of red cards and queens is $26 + 2 = 28$

Now for the probability of event = $\dfrac{{{\text{Favourable outcomes }}}}{{{\text{Total number of outcomes }}}}$

Favourable outcomes = $28$ Total number of outcomes =$52$

Probability = $\dfrac{{28}}{{52}}$ = $0.5384$

Now for the venn diagram

So from the venn diagram Probability is equal $\dfrac{{{\text{Shaded Region }}}}{{{\text{Total area}}}}$ that is equal to $\dfrac{{28}}{{52}}$= $0.5384$

In the part (ii) Probability we have to find neither jack nor spade

Total number of cards in a pack $52$

Total number of Spade cards in a deck of card is $13$

Total Jacks are $4$ in which $1$ are spade and $3$ are non- spade

Total number of spade card + Jack cards is $13 + 3 = 16$

Neither spade nor Jack cards = $52 - 16 = 36$

Now for the probability of event = $\dfrac{{{\text{Favourable outcomes }}}}{{{\text{Total number of outcomes }}}}$

Favourable outcomes = $36$ Total number of outcomes =$52$

Probability = $\dfrac{{36}}{{52}}$ = $0.72$

Now for the venn diagram

**Note:**

In a deck of cards , All cards are divided into 4 suits. There are two black suits — spades and clubs and two red suits — hearts and diamonds.

Probability of any event always lies between $0$ to $1$. If your answer comes apart from this then cross check it.
